13 But we will not boast of things without our measure, but according to the measure of the rule which God hath distributed to us, a measure to reach even unto you.
[AD 215] Clement of Alexandria on 2 Corinthians 10:13
), which is the perfection of faith, goes beyond catechetical instruction, in accordance with the magnitude of the Lord's teaching and the rule of the Church.

[AD 220] Tertullian on 2 Corinthians 10:13
Touching such, however, as are betrothed, I can with constancy "above my small measure" pronounce and attest that they are to be veiled from that day forth on which they shuddered at the first bodily touch of a man by kiss and hand.

[AD 258] Cyprian on 2 Corinthians 10:13
