Lucas 21

Lucas 21:8

And indeed, although we grieve at the destruction of these men, especially that after having once learned the doctrine of the Church, they have now gone back; yet we do not wonder at it; for this very thing Hymenaeus and Philetus suffered, and before them Judas, who, though he followed the Saviour, afterwards became a traitor and an apostate. Moreover, concerning these very men, warnings are not wanting to us, for the Lord foretold: "Take heed that ye be not deceived: for many shall come in My flame, saying, I am Christ; and the tithe draweth near: go ye not therefore after them." — Epistles on the Arian Heresy, Epistle Catholic 5
