And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offense of the cross ceased.
All Commentaries on Galatians 5:11 Go To Galatians 5
Augustine of Hippo
AD 430
Since he speaks of a stumbling block here, he is reminding them that the principal reason for the Jews’ taking offense at Christ was that they often saw him ignoring and disdaining those ceremonial observances which they believed themselves to have for their very salvation. What he says here, then, is as much as to say: “It was therefore in vain that the Jews in their indignation crucified Christ when he disdained these commandments. Now they still try to enjoin such things on those for whom he was crucified.”
