John Chrysostom
But we act as though we had suffered some great offense. We treat those who ask with contempt and turn away from them. You give nothing and cause grief.
Paul said, admonish them (2 Thess 3:15) as brothers (ἀδελφούς), “and do not revile them as enemies” (οὐχ ὑβρίζετε ώς ἐχθρούς).
One who admonishes his brother does this not openly and does not display arrogance. He does it privately, with great care, sorrowing and with tears in his eyes.
Therefore we give from a brotherly soul and instruct with a brotherly disposition. We do not grieve over the gift, but lament that he has transgressed the commandment, contrary to his own benefit.
If you insult while giving, you spoil the joy of the gift. But if you do not give and also revile, what evil you do to that poor, unfortunate man!

Instead of the text usually read in the manuscripts, μὴ ώς ἐχθρόν ήγεῖσθε, translated in Slavonic as “do not regard him as an enemy.”
