ACC ~ Galatians 6 v11

WITH MY OWN RECOGNIZABLE HAND I WRITE. JEROME: Those who wanted the Galatians to be circumcised had put it about that Paul preached one way and acted another, destroying his words by his own deeds, since he who proclaimed the abolition of the law was found to be obeying the law. Because Paul could not refute their opinions in person in the sight of all (being prevented by the chains that he bore as a testimony to Christ), he acts as his own lawyer through his letter. So that no suspicion that the letter was false might arise, he himself has written it from this point right to the end, showing that the preceding part was copied by another’s hand. … It is not that the letters were larger (though indeed the word would bear this sense in Greek) but because the marks of his own handwriting were known to them. So when they recognized the angles and contours of his own letters, they would feel that they had encountered him. … Paul wrote his letter in great characters because the meaning of the characters was great and had been traced out by the Spirit of God, not merely by pen and ink. EPISTLE TO THE GALATIANS 3.6.11.

TO STOP THE SLANDER. CHRYSOSTOM: Observe what great grief occupies that blessed soul [Paul]. … Having said a little about morals, he now returns to the things that were causing the greatest disturbance to his soul, saying “See in what large letters I have written to you.” Here he hints at nothing except that he himself wrote the whole letter, which is a sign of the greatest authenticity. For in the other epistles he may have composed, but another wrote. … By “so large” he seems to me to be indicating not the size but the poor form of the characters, all but saying, “Although I do not write well, I have nonetheless been compelled to write for myself, so as to silence those who slander me.” HOMILY ON GALATIANS 6.11.
