Paul's Words in Scripture are Christ's Words - Chrysostom

If they hear the shout of Paul, I am sure that they will easily fall into the nets of salvation and will put aside all the error of the Jews. For it is not Paul who spoke, but Christ, who moved Paul's soul. So when you hear him shout and say: "Behold, I, Paul, tell you," (Galatians 5:2) consider that only the shout is Paul's; the thought and the teaching are Christ's, who is speaking to Paul from within his heart.
