In the Gospel reading for Mass today our Lord teaches us the following,
For if you forgive men their trespasses, your heavenly Father also will forgive you; but if you do not forgive men their trespasses, neither will your Father forgive your trespasses.
Matthew 6:14-15, RSV-CE
This He said immediately after He taught His followers the Pater Noster in the midst of the Sermon on the Mount. I want to focus on these verses from 6:14-15 because they should not be overlooked. With these words Jesus is reiterating what He said just a few verses previous in the Pater Noster. In the twelfth verse Jesus said, “And forgive us our debts, as we also have forgiven our debtors.” And, of course, in our praying of the Pater Noster we change ‘debt’ to ‘trespass’. Even though we change debt to trepass for reciting the Pater Noster the words for debts/debtors in the Greek text of verse 12 are not the same as words used for trepasses in the Greek text of verses 14-15. Nevertheless, in the context of the passage it does seem that Jesus is speaking of the same thing in both verse 12 and verses 14-15: trepasses or sins.
