8 But now if we turn our attention to ourselves, if we think of His Body, how that we are even He. For if we were not He, “Forasmuch as you have done it unto one of the least of Mine, you have done it unto Me,” would not be true. If we were not He, “Saul, Saul, why do you persecute Me?” would not be true. So then we are He, in that we are His members, in that we are His Body, in that He is our Head, in that Whole Christ is both Head and Body. Peradventure then He foresaw us that we were not to keep the feast days of the Jews, and this is, “I go not up to this feast day.” See neither Christ nor the Evangelist lied; of the which two if one must needs choose one, the Evangelist would pardon me, I would by no means put him that is true before the Truth Himself; I would not prefer him that was sent to Him by whom he was sent. But God be thanked, in my judgment what was obscure has been laid open. Your piety will aid me before God. Behold, I have, as I was best able, resolved the question, both concerning Christ and the Evangelist. Hold fast the truth with me as men who love it, embrace charity without contention.
