O trumpet of peace to the soul that is at war! O weapon that puttest to flight terrible passions! O instruction that quenches the innate fire of the soul! The Word exercises an influence which does not make poets: it does not equip philosophers nor skilled orators, but by its instruction it makes mortals immortal, mortals gods; and from the earth transports them to the realms above Olympus. Come, be taught; become as I am, for I, too, was as ye are.
This is addressed to his Jewish disciples, and he brings his own example forward, to induce them thereby to abandon their old customs. Though you had none other for a pattern, he says, to look at me only would have sufficed for such a change, and for your taking courage. Therefore gaze on me; I too was once in your state of mind, especially so; I had a burning zeal for the Law; yet afterwards I feared not to abandon the Law, to withdraw from that rule of life. And this ye know full well how obstinately I clung hold of Judaism, and how with yet greater force I let it go. He does well to place this last in order: for most men, though they are given a thousand reasons, and those just ones, are more readily influenced by that which is like their own case, and more firmly hold to that which they see done by others.
Observe how he again addresses them by a title of honor, which was a reminder moreover of the doctrine of grace. Having chid them seriously, and brought things together from all quarters, and shown their violations of the Law, and hit them on many sides, he gives in and conciliates them speaking more tenderly. For as to do nothing but conciliate causes negligence, so to be constantly talked at with sharpness sours a man; so that it is proper to observe due proportion everywhere. See then how he excuses to them what he has said, and shows that it proceeded not simply because he did not like them, but from anxiety. After giving them a deep cut, he pours in this encouragement like oil; and, showing that his words were not words of hate or enmity, he reminds them of the love which they had evinced toward him, mixing his self-vindication with praises. Therefore he says, "ye did me no wrong."
He is saying something like this: “Just as I was made weak for your weakness and could not speak as to spiritual people … so you should also be as I am, that is, understand more spiritually.” … This he says indeed as an imitator of the Savior, who … “was found in fashion as a man,” that we might come to the divine life from being men.
A disciple harms his master if he wastes his precepts and his work by his own neglect. The Galatians had not harmed the apostle, because they had observed his gospel and his commands right up to the present.… Or else [he means]: “When I first preached the gospel to you … I pretended to be weak that I might be helpful to you in your weakness; did you not receive me as an angel, as Christ Jesus? When, therefore, you did me no harm at that time and thought me in my downcast and lowly state to be like the Son of God, why am I harmed by you when I stir you up to greater things?”
(Verse 12) Be as I am, for I am also as you are. What he says is such, as I became weak to you who are weak, and I could not speak to you as spiritual, but as carnal and as little ones in Christ, and because you were not yet able to eat solid food, I fed you with only milk, not wanting you to remain in infancy forever, but gradually leading you to adolescence and youth, so that you could receive solid food. Thus, you should also be as I am, to have a more perfect understanding, leaving behind milk and moving on to stronger food, and to greater nourishment. But he speaks as if he were an imitator of the Savior, who did not consider equality with God as something to be seized, but emptied himself, taking the form of a servant; he was found in appearance as a man, so that we might become gods from humans, and no longer die; but rising with Christ, we are called his friends and brothers, and to be his disciples as the master, and servants as the Lord. But it can also be understood this way: I beseech you, he says, brothers, that you imitate me, who, without complaint, lived by the Law, considering everything as rubbish and garbage, so that I may gain Christ. For indeed I myself, like you now are, was held fast by the same strict observances and I persecuted and ravaged the Church of Christ because it did not follow these things.
To the believers from among the Jews he speaks thus: imitate me. For I too was very devoted to the law, as you are, but I left it and now contend for Christ and the faith. Be such as these yourselves. He expressed this beautifully in conclusion. For people are more readily drawn by kindred examples than by arguments.
After strong reproaches, he again displays gentleness. For harsh censure is no more beneficial than extreme leniency. Therefore he calls them brethren, reminding them at the same time of the grace of baptism, by which we all became brethren, as born of one Father – God. He also justifies the reproaches he has expressed, namely that they did not arise from hatred. For you have done me no injustice that I should become hostile toward you, but rather, you have shown me countless signs of honor and affection. How then, after this, could I be saying these things out of hatred? But I speak, without doubt, out of concern for you and out of deep gratitude toward you.
