Mark 10:18 — “No one is good except God alone”: Jesus distinguishes himself from the one good God

“And as he was setting out on his way, a man ran up, knelt before him, and asked him: Good Teacher, what must I do to inherit eternal life? But Jesus said to him: Why do you call me good? No one is good except God alone.”

Mark 10:17-18

Context: The Rich Man’s Question about Eternal Life

Mark 10:18 stands at the beginning of Jesus’ encounter with a rich man who asks about the way to eternal life (10:17-22). The questioner approaches with great reverence: he runs up, kneels down, and addresses Jesus as “good Teacher” (didáskale agathé). It is precisely at this address that Jesus takes hold. Before he answers the actual question, he rejects the predicate “good”: “Why do you call me good? No one is good except God alone.”

The rejection is no subordinate aside but a deliberate clarification placed before the answer. Jesus turns the man’s gaze away from the “good Teacher” and toward the one who alone is good: God. Only afterward does he point to the commandments (10:19) — that is, to the will of this very one God. The whole scene is theocentrically oriented: not Jesus himself, but God and his commandment stand at the center of the question of salvation.

The passage has three synoptic versions. Mark 10:18 and Luke 18:19 agree word for word: “Why do you call me good? No one is good except God alone.” Matthew 19:17 phrases it strikingly differently: “Why do you ask me about what is good? One there is who is good.” This reshaping in Matthew is telling both text-critically and in the history of interpretation — it already shows an early embarrassment over the Markan wording, which so clearly distinguishes Jesus from the “one who alone is good.”

Within the structure of Mark’s Gospel, 10:18 fits into a series of passages in which Jesus places the Father above himself and subordinates himself to him: “but concerning that day no one knows … not even the Son, but only the Father” (Mk 13:32); “Hear, O Israel: the Lord our God, the Lord is one” (Mk 12:29); “not what I will, but what you will” (Mk 14:36). Mark 10:18 is the keynote of this line: the one God alone is good, and Jesus points to him.

Socinian Core Thesis

Socinianly, Mark 10:18 is plainly and literally true and requires no resolution by a doctrine of two natures. Jesus deflects the predicate “good” in the absolute, proper sense away from himself and reserves it for the one God. When he says “no one is good except God alone,” he precisely does not equate himself with this one God, but distinguishes himself from him. The “alone” (heís, “one”) excludes there being, alongside the one good God, a second, equally good one.

The decisive point is the meaning of “good” in this place. Jesus does not deny that he is good in the ordinary, human sense, indeed perfectly sinless. Rather, he rejects “good” in that highest sense in which it is a divine predicate: the good that is from itself, original, absolute. In this sense God alone is good — just as he alone is wise, alone immortal, alone the supreme Lord. These predicates stand and fall together: whoever is good of himself is so as the one God.

The goodness of Christ is accordingly a received, derived goodness. All that is good and perfect in him he has from the Father, “who alone is good” (cf. Jas 1:17: “every good gift … comes down from above, from the Father of lights”). Jesus himself directs the questioner to this source: not the “good Teacher” is the final point of reference, but the one good God, whose commandments lead to life.

Thus the passage also answers the question of Jesus’ relation to God in exactly the reverse way from how the doctrine of the Trinity reads it. Had Jesus wished to attest his consubstantiality with God, this would have been the place to accept the “good”: “You rightly call me good, for I am God.” Instead he rejects it and points to the one. John 17:3, 1 Corinthians 8:6, and John 20:17 speak the same language: the Father alone is the one, true God, the God also of Jesus Christ.

Core Statement

Key Terms

Four linguistic observations decide the interpretation of Mark 10:18:

agathós — “good” in the absolute sense

The Greek agathós denotes the good, the excellent, the morally perfect. Jesus uses the word here in its highest, absolute sense: the absolutely, from-itself good. In this sense it is a predicate of God — just as Scripture calls God “only wise” (Rom 16:27), “alone immortal” (1 Tim 6:16), and “alone holy” (Rev 15:4). Jesus does not deny his moral perfection; he rejects the word in that absolute meaning in which it belongs to God alone.

The distinction between derived and original goodness is the key. Human beings can be called “good” — “the good person produces good out of the good treasure of his heart” (Lk 6:45). But this goodness is received and derived. The goodness that is from itself, the source of all goodness, is God alone. It is precisely this that Jesus means when he says: “No one is good except God alone.”

heís ho theós — “one: God”

The Greek closing clause reads oudeís agathós ei mê heís ho theós — literally: “no one is good except one: God.” The numeral heís (“one”) is emphatic. It is the same word with which the “Hear, O Israel” confesses the one God (kýrios heís estin, Mk 12:29). Jesus thus places “good” under the same “one” that expresses the strict singularity of God: good is one, namely God.

This “one” leaves no room for a second, equally good one alongside the first. If Jesus himself were the one good God, he would have to accept the predicate, not reject it. By rejecting it and reserving it for the “one” from whom he distinguishes himself in the same sentence (“why do you call me good?”), he places himself on the side of those who receive the good, not on the side of the one who is it from himself.

ti me légeis — “why do you call me …?”

The counter-question ti me légeis agathón (“why do you call me good?”) is no mere formula of modesty. It is a genuine query that compels the questioner to reflect on the word “good.” Jesus asks, as it were: “Do you know what you are saying when you call me ‘good’? This word in its full sense belongs to God alone.” The question turns the gaze away from the teacher and toward God.

That Jesus deems such a correction necessary at all is significant. Had he been conscious of consubstantiality with God and wished to teach it, the address “good Teacher” would have been an occasion to confirm it. Instead he corrects and directs goodness wholly toward God. The early reshaping of this question in Matthew 19:17 (“why do you ask me about what is good?”) shows that the early church already felt the sharpness of the Markan wording.

“alone” — the series of God’s sole-predicates

Mark 10:18 belongs to a series of passages that ascribe a predicate exclusively to God: God is “good alone” (Mk 10:18), “only wise” (Rom 16:27), “alone immortal” (1 Tim 6:16), “alone holy” (Rev 15:4), “the only true God” (Jn 17:3), “alone sovereign” (1 Tim 6:15). These sole-predicates form a closed field: they characterize the one who possesses the respective perfection from himself and in unlimited measure.

It is telling that the Trinitarian interpretation does not consistently extend these sole-predicates to the Son. No one infers from “God alone is wise” that the Son is therefore not wise; or from “God alone immortal” that the Son is mortal-in-the-proper-sense. One reads these predicates as statements about the one God, from whom the rest receive their share. Exactly so is “God alone is good” to be read: as a statement about the one from whom Jesus has received all that is good.

Comparison of the Interpretations

Sozzini in the Original: The Racovian Catechism on the Goodness of the One God

The Racovian Catechism, in its section on the nature of God, explicitly treats the question of why Scripture can on the one hand speak of “gods” and on the other confess only one God. Its answer links being-good directly with aseity — with having-from-oneself — and thereby makes it the mark of the one God:

“For this very reason, because that One alone has dominion from himself and is wholly the head, while all the rest depend only on him and owe their dominion to his goodness; in which sense he is also called alone wise, alone immortal, and no one is good except that One.”

Racovian Catechism (1605), The Nature of God — God’s Existence and Unity

The catechism expressly ranks the “no one good except that One” in the series of sole-predicates: alone wise, alone immortal, alone good. And it names the reason: that One has dominion “from himself,” while “all the rest depend only on him.” With this the very logic of Mk 10:18 is articulated: good in the absolute sense is only he who is from himself; all others who have something good have received it. Jesus, who deflects the “good” away from himself, places himself on the side of the receivers.

This distinction between original and received divinity the catechism unfolds more fully elsewhere. It separates the proper from the improper use of the word “God”:

“The word Deus is used in the Scriptures chiefly in two ways: the first way obtains when it designates him who rules and governs over all things in heaven and on earth in such a way that he acknowledges no one above himself, who is the author and origin of all things, so that he depends on no one, and who possesses one simply infinite power. In this meaning Scripture asserts that God is one.”

Racovian Catechism (1605), The Twofold Use of the Word “God” in Scripture

God in the proper sense — he who “acknowledges no one above himself” and “depends on no one” — is one. It is precisely this one who is “good alone.” Jesus, however, throughout confesses a God above himself (“my God and your God,” Jn 20:17; “the Father is greater than I,” Jn 14:28) and his dependence on him (“the Son can do nothing of his own accord,” Jn 5:19). He therefore precisely does not belong to that one of whom the “good alone” holds.

Consistently, the catechism acknowledges in Christ no divine nature in the sense of the divine essence: “Insofar as we here understand by the name of divine nature or substance the essence of God himself, in this sense we acknowledge no divine nature in Christ, since this is contrary not only to sound reason but also to Holy Scripture.” What is divine and good in Christ is conferred on him by God — not from his own, original essence.

Overview of the writings of Sozzini

Logical Arguments

From Mark 10:18 the following theological-philological arguments against the consubstantiality of the Son with the Father arise:

1. Argument from the rejection. Jesus rejects the predicate “good” (“why do you call me good?”) instead of accepting it. Had he wished to teach consubstantiality with the God who alone is good, this would have been the place to confirm the “good.” The rejection makes sense only if Jesus distinguishes himself from the one good God.
2. Argument from the ‘one.’ “No one is good except one: God” (heís ho theós). The emphatic “one” is the same numeral as in the “Hear, O Israel” (Mk 12:29). It leaves no room for a second, equally good God alongside the first. But a consubstantial second divine being would be just such a second good one.
3. Argument from self-distinction. Jesus says “why do you call me good? No one is good except God” — he thus sets “me” and “God” over against each other in the statement. He expressly distinguishes himself from the one who alone is good. Were he himself this one good God, the opposition would be senseless.
4. Argument from aseity. According to the Racovian Catechism, God is “good alone” because he has goodness “from himself,” while all the rest receive it. Absolute goodness is a predicate of aseity. Jesus, who receives everything from the Father (Jn 5:19, 26), has received his goodness — and thereby belongs on the side of the dependent.
5. Argument from the series of sole-predicates. “Good alone” stands beside “only wise” (Rom 16:27), “alone immortal” (1 Tim 6:16), “the only true God” (Jn 17:3). These predicates throughout characterize the one God, the Father, from whom the rest receive their share. “Good alone” is to be read no differently.
6. Argument from the testimony of Matthew. Matthew 19:17 reshapes the question (“why do you ask me about what is good? One there is who is good”), evidently because the Markan wording was felt to be offensive. This early smoothing indirectly attests how clearly the original wording distinguishes Jesus from the God who alone is good.
7. Argument from the theocentric aim. The whole scene turns the questioner’s gaze away from Jesus and toward God and his commandments (10:19). Not the “good Teacher” is the final point of reference of the question of salvation, but the one good God. A reading that derives Jesus’ deity from the verse inverts the direction of the passage.
8. Argument from the continuous Markan line. Mark portrays Jesus throughout as subordinate to the Father: he does not know the day (13:32), he prays “not what I will” (14:36), he confesses the one Lord (12:29). Mark 10:18 fits in seamlessly. The few passages from which deity is read are to be interpreted from this broad line, not the reverse.
9. Argument from received goodness. Scripture knows “good” persons (Lk 6:45; Acts 11:24: Barnabas, “a good man”) without holding them to be God. Their goodness is derived. The perfect goodness of Christ too is received: “every good gift comes down from above, from the Father of lights” (Jas 1:17). This does not include the absolute, from-itself goodness that God alone is.

Biblical Cross-References

The following passages support, deepen, or illuminate the Socinian interpretation of Mark 10:18:

Objections and Socinian Answers

Objection 1: “Jesus does not reject the ‘good,’ but leads the questioner to the conclusion that he — being good — is precisely God.”

First, the wording does not bear this inverse inference. Jesus says “no one is good except one: God” — thereby setting “me” and “God” over against each other instead of equating them. Whoever reads an equation out of this express distinction turns the sentence into its opposite. The text precisely does not suggest the inference “therefore I am God,” but wards off the premature predicate.

Second, this “hidden proof” is a later construction that remains external to the passage. Had Jesus wished to lead the questioner to the conclusion “you are God,” the obvious thing would have been to accept the “good” and explain it, instead of rejecting it. The rejection first creates the difficulty that the objection then seeks to remove by an artificial syllogism.

Third, the alleged proof of deity does not fit the course of the scene. Jesus does not lead the man to himself but to the commandments of God (10:19) and finally to discipleship (10:21). The aim is theocentric and ethical, not christological-speculative. An interpretation that finds here a proof of Jesus’ deity foists an alien interest on the passage.

Fourth, the early reshaping in Matthew 19:17 already attests that the early church saw in the Markan wording no convenient testimony to deity, but a sharpness it sought to soften. Had the verse taught Jesus’ deity, it would not have needed to be reshaped, but would gladly have been retained word for word.

Objection 2: “The rejection holds only according to Christ’s human nature.”

First, the text does not make this distinction. Jesus does not say “my human nature is not good in the highest sense,” but rejects the address altogether from “me”: “why do you call me good?” The subject is the whole speaking person, not one of its assumed natures. The split into two natures is an addition of the interpreter, not a statement of the verse.

Second, the evasion is a petitio principii: it presupposes the disputed second, divine nature in order to defuse the verse, which precisely speaks against such a from-itself good nature in Christ. One cannot refute a testimony by simply assuming as given the very doctrine called into question by the testimony.

Third, the two-natures reading makes the rejection meaningless. Were Jesus, according to a divine nature, the God who alone is good, then the address “good Teacher” would indeed be apt — and there would be no reason to reject it. Only the insight that Jesus is not the one, absolutely good God makes his correction intelligible.

Fourth, the rule of predication-logic holds: what is asserted of a person absolutely and without restriction may not afterward be limited to a part. “No one is good except God alone” is an absolute statement; the “me” from which Jesus deflects the “good” is the whole person of the speaker, not a separated nature.

Objection 3: “Elsewhere Jesus is called ‘the good shepherd’ (Jn 10:11). So he is good after all — and therefore God.”

First, the very choice of words distinguishes. In Jn 10:11 stands kalós (beautiful, excellent, exemplary), in Mk 10:18 by contrast agathós in the absolute sense of from-itself goodness. The “good shepherd” is the exemplary shepherd who gives his life — a statement about his office and conduct, not about a divine essential predicate.

Second, Mk 10:18 does not deny the derived goodness of Christ at all. Jesus is in the highest degree good, perfect, sinless — but in a received manner, not of himself. Scripture also calls human beings good: Barnabas is called “a good man” (Acts 11:24), and “the good person produces good” (Lk 6:45). No one therefore holds them to be God. Derived goodness proves no deity.

Third, Mk 10:18 expressly concerns the “good alone” — the goodness that one has, namely God. That Jesus is good does not contradict this, so long as his goodness is understood as received. Only the assertion that Jesus is good of himself, that is, the one good God himself, would come into conflict with the verse — and precisely this assertion Jesus rejects.

Fourth, the “good shepherd” even confirms the Socinian reading, for the shepherd gives his life “at the Father’s charge” (Jn 10:18): “This charge I have received from my Father.” The goodness of the shepherd too thus stands under receiving from the Father — wholly in the sense of the dependence that Mk 10:18 expresses.

Objection 4: “Jesus does not censure the ‘good,’ but the superficial attitude of the questioner.”

First, Jesus does indeed give a substantive reason, not merely an attitude: “No one is good except God alone.” That is a statement about the matter — about the predicate “good” and its belonging to God — not merely a censure of manner. The questioner is referred to the one good God, not to better manners.

Second, one may not play off the theological statement against the pastoral one. To be sure, Jesus also corrects the thoughtless address; but he does so by making a true statement about God. Both belong together: the pedagogical turn happens through a substantive clarification, and this clarification is that God alone is good.

Third, it would be methodologically arbitrary to declare precisely this sentence a mere formula, while from far less clear passages one derives far-reaching essential statements. If “no one is good except God alone” may say nothing about Jesus’ relation to God, then one would have to exercise the same restraint with many other sentences.

Fourth, the statement fits into the continuous line of Jesus’ self-testimonies that place the Father above himself (Mk 13:32; 14:36; Jn 14:28; 20:17). It is no isolated slip and no mere bon mot, but part of a broad, unified attestation of the Son’s subordination to the one God.

Objection 5: “If Jesus were not good in the highest sense, he could not be Redeemer.”

First, the objection confuses derived and original goodness. Mark 10:18 does not deny Jesus the perfect, indeed sinless goodness, but only the from-itself, original goodness that God alone has. For the work of salvation the perfect received goodness of the man Jesus, sent and sanctified by God, suffices and is fitting.

Second, Scripture itself locates the efficacy of salvation not in a from-itself deity of Christ, but in God’s acting through him. God “attested” Jesus “by deeds that God did through him” (Acts 2:22); God raised him and “made him Lord and Christ” (Acts 2:36). The Redeemer works out of the authority conferred on him, not out of an own divine essence.

Third, the Socinian reading honors the work of salvation no less, but directs its honor to the right place: to the one good God, who saves in Christ and through Christ. “All this is from God, who reconciled us to himself through Christ” (2 Cor 5:18). The ultimate source of salvation is the goodness of the Father, which shows itself in Christ.

Fourth, the objection, consistently applied, would devalue every messenger used by God. Yet Scripture knows many through whom God worked great things without their being divinely good of themselves. Christ is the greatest and most perfect among them — the appointed Lord and Judge (Acts 10:42) — but his rank as Redeemer is given him by the one good God, not his own from himself.

Summary

Mark 10:18 — “Why do you call me good? No one is good except God alone” — is a statement of distinction, not of equation. To the address “good Teacher,” Jesus deflects the predicate “good” in the absolute, divine sense away from himself and reserves it for the one God: oudeís agathós ei mê heís ho theós. The emphatic “one” (heís) is the same word as in the “Hear, O Israel” and leaves no room for a second, equally good God. Jesus sets “me” and “God” over against each other and thereby expressly distinguishes himself from the one who alone is good.

The Racovian Catechism (1605) adduces precisely this “no one good except that One” as the mark of the one God, who has dominion “from himself,” while “all the rest depend only on him.” The “good alone” thus stands in a series with “only wise,” “alone immortal,” and “the only true God” — predicates of the one God, from whom all else receives its share. The goodness of Christ is accordingly perfect, but received: “every good gift comes from above, from the Father of lights” (Jas 1:17).

Socinianly, the saying is plainly and literally true and fits into the continuous line of Jesus’ self-testimonies that place the Father above himself (Mk 12:29; 13:32; 14:36; Jn 5:19; 14:28; 20:17). Jesus is not the one, only good God, but the Son sent by him and endowed with all authority, who reserves the highest predicate for the one God and leads the questioner to him.
