John Chrysostom
Catena Aurea · Lukasevangelium 11
And it came to pass, that, as he was praying in a certain place, when he ceased, one of his disciples said unto him, Lord, teach us to pray, as John also taught his disciples. And he said unto them, When ye pray, say, Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so in earth. Give us day by day our daily bread. And forgive us our sins; for we also forgive every one that is indebted to us. And lead us not into temptation; but deliver us from evil.
Considering then these things, we ought to shew mercy to our debtors. For they are to us if we are wise the cause of our greatest pardon; and though we perform only a few things, we shall find many. For we owe many and great debts to the Lord, of which if the least part should be exacted from us, we should soon perish.
