But ye have not so learned Christ;

But ye did not so learn Christ;

But ye have not thus learnt the Christ,

For this was not the teaching of Christ which was given to you;

But far different is the lesson you learned from the Christ – if, that is, you really listened to him,

Vos autem non ita didicistis Christum;

But ye have not. He now draws a contrast of a Christian life, so as to make it evident how utterly inconsistent it is with the character of a godly man to defile himself regardlessly with the abominations of the Gentiles. Because the Gentiles walk in darkness, therefore they do not distinguish between right and wrong; but those on whom the truth of God shines ought to live in a different manner. That those to whom the vanity of the senses is a rule of life, should yield themselves up to base lusts, is not surprising; but the doctrine of Christ teaches us to renounce our natural dispositions. He whose life differs not from that of unbelievers, has learned nothing of Christ; for the knowledge of Christ cannot be separated from the mortification of the flesh.

But ye have not so learned Christ - You have been taught a different thing by Christ; you have been taught that his religion requires you to abandon such a course of life.

But ye have not so learned Christ - Ye have received the doctrines of Christianity, and therefore are taught differently; ye have received the Spirit of Christ, and therefore are saved from such dispositions. Some would point and translate the original thus: Ὑμεις δε ουχ οὑτως· εμαθετε τον Χριστον· But ye are not thus; ye have learned Christ.

(13) But ye have not so learned Christ;
(13) Here follows the contrary part concerning men who are regenerated by the true and living knowledge of Christ, who have other principles by which they act that are very different, that is, holy and honest desires, and a mind completely changed by the power of the Holy Spirit, from which proceeds also like effects, as a just and holy life indeed.

But ye have not so learned Christ,.... Some distinguish these words, and make two propositions of them, "but ye not so", or "ye are not so, ye have learned Christ"; the first of these propositions has respect to what goes before, and suggests that regenerate persons are not as other men: they do not walk in the vanity of their minds as others, their minds are not empty and vain; but are filled with God, with a saving knowledge of God in Christ, with the fear and love of God, and with Christ, with a spiritual knowledge of him, with faith in him and love to him, and with the Spirit, with his graces and fruits of righteousness; and though there is a great deal of vanity, instability, treachery, and sinfulness in them, yet their walk and the course of their conversation is not according to this: nor are their understandings darkened as others; they are enlightened to see their lost state and condition by nature, the plague of their own hearts, the insufficiency of their own righteousness, the way of life and salvation by Christ, and that salvation from first to last is all of grace; they have some light into the doctrines of the gospel, and have some glimpse of glory; and their light is of an increasing nature: they are not alienated from the life of God as others, but live a life of communion with him, a life of faith upon him, and a life of holiness according to his mind; they are not past feeling as others, they are sensible of sin, and are often pressed down with the weight of it, and groan, being burdened by it; they cannot sin with that delight and pleasure as others do, nor will they plead for it, but confess it with shame and sorrow; nor do they give up themselves to it, and continue in it, and in an insatiable pursuit of it: the reason of all which is, they "have learned Christ": so as to know him as God over all blessed for ever; as the Lord and heir of all things; as the Alpha and Omega of the covenant of grace; as intrusted with all that is near and dear to his Father; as the Father's free gift to men, and as the sinner's Saviour; as the way of access to God and acceptance with him; as the church's head and husband; as the saints' prophet, priest, and King, and as the only Mediator between God and men; and so as to receive him, believe in him, and commit their souls unto him; and so as to embrace his truths, and submit to his ordinances: and this lesson they learn, not in the book and school of nature, nor of carnal reason, nor of the law; but in the book of the covenant, and of the Scripture; and in the school of the church, and under the ministry of the Gospel; for the ministers of the Gospel are the instructors, the instruments of teaching; though the Spirit of God is the efficient cause, the anointing which teacheth all things, and leads into all truth, as it is in Jesus: and this lesson being truly learnt, will teach men to walk differently from others; to deny ungodliness and worldly lusts, and to live soberly, righteously, and godly.

learned Christ-- (Philippians 3:10). To know Christ Himself, is the great lesson of the Christian life: this the Ephesians began to learn at their conversion. "Christ," in reference to His office, is here specified as the object of learning. "Jesus," in Ephesians 4:21, as the person.

But ye have not so learned Christ. You are Gentiles by birth, like those just described, but you have learned otherwise from Christ.
If so be that ye have heard him. This does not express a doubt that they had heard and been taught by Christ. The idea is: If ye have heard, etc., as I know you have, you have been taught the truth in Jesus, that (Ephesians 4:22) ye put off concerning the former manner of life the old man and his deeds. "The old man" is the old sinful life, in contrast with "the new man," or new life in Christ.
And be renewed. That is, be made new by having a new mind, or spirit. See Romans 12:2.
And that ye put on the new man. He who has a new mind within him is a new man. He who is born anew, "of water and of the Spirit" (John 3:5), is newly created in righteousness. This is still part of what they were taught (Ephesians 4:21). The new creation described took place at conversion.

But ye have not so learned Christ - That is, ye cannot act thus, now ye know him, since you know the Christian dispensation allows of no sin.
