1 The lesson of the holy Gospel which preceded today's had concluded thus: that “the Lord spoke, teaching in the treasury,” what it pleased Him, and what you have heard; “and no one laid hands on Him, for His hour was not yet come.” Accordingly, on the Lord's day we made our subject of discourse what He Himself thought fit to give us. We indicated to your Charity why it was said, “His hour was not yet come,” lest any in their impiety should have the effrontery to suspect Christ as laid under some fatal necessity. For the hour was not yet come when by His own appointment, in accordance with what was predicted regarding Him, He should not be forced to die unwillingly, but be ready to be slain.
