VERSES 13, 14. Ye know how through infirmity of the flesh I preached the gospel unto you at the first. And my temptation which was in my flesh ye despised not, nor rejected; but received me as an angel of God, even as Christ Jesus.
"You Galatians were very good to me. When I began to preach the Gospel to you in the infirmity of my flesh and in great temptation you were not at all offended. On the contrary, you were so loving, so kind, so friendly towards me, you received me like an angel, like Jesus Himself."
Indeed, the Galatians are to be commended for receiving the Gospel from a man as unimposing and afflicted all around as Paul was. Wherever he preached the Gospel, Jews and Gentiles raved against him. All the influential and religious people of his day denounced him. But the Galatians did not mind it. That was greatly to their honor. And Paul does not neglect to praise them for it. This praise Paul bestows on none of the other churches to which he wrote.
St. Jerome and others of the ancient fathers allege this infirmity of Paul's to have been some physical defect, or concupiscence. Jerome and the other diagnosticians lived at a time when the Church enjoyed peace and prosperity, when the bishops increased in wealth and standing, when pastors and bishops no longer sat over the Word of God. No wonder they failed to understand Paul.
When Paul speaks of the infirmity of his flesh he does not mean some physical defect or carnal lust, but the sufferings and afflictions which he endured in his body. What these infirmities were he himself explains in 2 Corinthians 12:9-10 : "Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong." And in the eleventh chapter of the same Epistle the Apostle writes: "In labors more abundant, in stripes above measure, in prisons more frequent, in deaths oft. Of the Jews five times received I forty stripes save one. Thrice was I beaten with rods, once was I stoned, thrice I suffered shipwreck," etc. (2 Corinthians 11:23-25.) By the infirmity of his flesh Paul meant these afflictions and not some chronic disease. He reminds the Galatians how he was always in peril at the hands of the Jews, Gentiles, and false brethren, how he suffered hunger and want.
Now, the afflictions of the believers always offend people. Paul knew it and therefore has high praise for the Galatians because they over looked his afflictions and received him like an angel. Christ forewarned the faithful against the offense of the Cross, saying: "Blessed is he, whosoever shall not be offended in me." (Matthew 11:6.) Surely it is no easy thing to confess Him Lord of all and Savior of the world who was a reproach of men, and despised of the people, and the laughing stock of the world. (Psalms 22:7.) I say, to value this poor Christ, so spitefully scorned, spit upon, scourged, and crucified, more than the riches of the richest, the strength of the strongest, the wisdom of the wisest, is something. It is worth being called blessed.
Paul not only had outward afflictions but also inner, spiritual afflictions. He refers to these in 2 Corinthians 7:5-6, "Without were fightings, within were fears." In his letter to the Philippians Paul makes mention of the restoration of Epaphroditus as a special act of mercy on the part of God, "lest I should have sorrow upon sorrow."
Considering the many afflictions of Paul, we are not surprised to hear him loudly praising the Galatians for not being offended at him as others were. The world thinks us mad because we go about to comfort, to help, to save others while we ourselves are in distress. People tell us: "Physician, heal thyself." (Luke 4:23.)
The Apostle tells the Galatians that he will keep their kindness in perpetual remembrance. Indirectly, he also reminds them how much they had loved him before the invasion of the false apostles, and gives them a hint that they should return to their first love for him.
