Therefore if you bring your gift to the altar, and there remember that your brother has anything against you;
All Commentaries on Matthew 5:23 Go To Matthew 5
Cyril of Alexandria
AD 444
The statement “if you should bring your gift” shows that this is conceived as a means of salvation and as an escape from punishment for sinners. For this God invented repentance. One will avert punishment, however, who tends to the feelings of another who has been wounded. But one who does not love his brother does not love the Lord. Hence it is fitting that whoever bears hard feelings toward his brother is not accepted, since he does not approach the Lord in truth.
