Why does Saint Paul remind them of this? Partly to continue the thought he had begun and to present it more fully. Since he had received no unpleasantness from them, he could not be speaking so sternly from resentment. He speaks only from love and a desire for their good. It is as though he said, “And why do I say, ‘You did not wrong me’? On the contrary, you showed great and heartfelt attachment to me. For you know, and so forth. Believe, then, that what has been said to you has not been said from irrational anger or passionate disturbance of soul, but only from care for your souls” (Chrysostom).
More than this, he reminds them in order to raise up in their souls the memory of how the first preaching went among them. He recalls how their souls were changed, how they left everything and cleaved to the Lord, and how they received the Apostle himself as one sent from above. In his person they saw the Lord Himself Who had sent him, as envoys are ordinarily received as the one who sent them.
The holy Apostle knew that if the same initial fire of zeal for the pure faith of Christ were kindled in their souls, it would cast out of them everything foreign to that faith. So molten metal drives out every alien substance from itself. Therefore he wants to renew that fire by compelling the Galatians to pass again in heart through the whole history of their conversion, which they had forgotten and which later events had obscured.
In the conversion of the Galatians, one must suppose, there was something extraordinary. Outwardly, Saint Paul appeared so humbled that one might even spit upon him. Yet he was received so highly, and such ardent faith was shown toward his word. The memory of this extraordinary manifestation of the power of God among them could powerfully sustain, and surely did sustain, the same spirit of faith in the Galatians, both in power and in content, just as a banner in regiments always inspires soldiers.
Surely this was so, but later it was little by little forgotten. Forgetfulness made it possible for the false teachers to creep into their souls. The holy Apostle now restores that memory in order to cast them out again from there, together with everything they brought in.
There is no pressing need to define precisely the words, “because of infirmity of the flesh,” which he immediately also calls “my trial in the flesh.” The holy Apostle only wishes to say, “Remember what I was like outwardly among you. Judging by human relations and notions, I was such that one might despise and spit upon me. But my teaching was luminous, exalted, and divine. Then you were able to distinguish the essence of a precious matter under my unattractive exterior. Was this essence, my Gospel, what you now understand it to be? Where has your keen sight gone, so that what you clearly saw in the twilight is now seen dimly by you in broad daylight?”
The interpreters nevertheless try to determine what infirmity of the flesh the Apostle had. Some think it was some bodily illness. Others think it was persecutions, reproaches, and wounds, which are more fittingly called “the trial in the flesh.”
Blessed Jerome writes: “We may suppose that the Apostle fell ill when he first came to the Galatians. Yet, although he was seized by illness, he did not cease preaching the Gospel. There is a tradition that he often suffered from a headache. This was the angel of Satan given to him to buffet him, lest he be exalted (cf. 2 Cor 12:7). This infirmity was a trial for those to whom the Gospel was proclaimed, whether they would despise the one who promised such lofty things while he himself was so weak in body. Nor is it inappropriate that, when the Apostle first came to the Galatians, he endured reproaches, persecutions, and wounds from those who opposed the Gospel. It must have been a great trial for the Galatians when they saw blows inflicted on the Apostle.”
The Eastern interpreters, however, all give the words “infirmity” and “trial” exclusively the latter meaning. Chrysostom says, “What does he wish to say by this? When I was preaching to you, he says, I was persecuted, scourged, and threatened with a thousand deaths. Even then you did not despise me. For this is what the words mean: ‘My trial which was in my flesh you did not despise nor reject.’”
At the same time one may also understand here a hidden reproach of the Galatians, which could not have remained unfelt by them. The thought must at once have come to them: “The Apostle suffered so much for us, and now we have turned our back on him. Is it not strange that at the beginning we received and honored him when he was despised, and afterward we withdrew from him? Shame on us!” “By this the Apostle also puts them to shame,” writes Theophylact, “reminding them how much he endured for their sake from those who opposed the truth.”
Chrysostom says, “Do you notice the Apostle’s spiritual wisdom? In the very act of justifying himself, he does not cease to reproach them, when he sets before them how much he suffered for them, and when he says, ‘Yet this did not scandalize you in the least. You did not spit upon me in these sufferings and persecutions.’ By infirmity and trial he means sufferings and persecutions. ‘But you received me as an angel of God.’ How, then, is it not strange now to receive one persecuted and pursued as an angel of God, but not to receive him when he teaches what is necessary?”
They received him as an angel, as Christ Jesus. This was because of the impression made by the preaching among them. By its power Christ Jesus had been so vividly portrayed in their mind that He seemed to hang crucified before their eyes. The word of the Apostles came from their mouths not according to their own desire and reasoning, but by the movement of the Spirit of God.
The extraordinary vividness of the word among the Galatians remained memorable to Saint Paul. It could not but remain memorable to the Galatians also. The Apostle leads them toward this with these words. For they had received him so highly because of the power of the preached word. This was to raise up in their souls everything that had taken place in them at their first conversion. As was already indicated above, this was very important for the holy Apostle’s aim.
Attention is also drawn to the preposition dia, in di’ astheneian, “because of infirmity.” It seems to mean that he preached because of infirmity of the flesh. He had not planned to preach, but illness detained him, and so he began to preach. Perhaps this was so. But it is better to translate it as we say, “through force,” or “through tears.” The meaning will be, despite illness, if there was illness, or despite persecutions and wounds, or amid illness and wounds. They continued, and I did my work, moving among them and through them, as one walks through thorns.
