Pseudo-Augustine
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.
(ubi sup.) For then cometh the kingdom of God, when we have obtained His grace. For He Himself says, The kingdom of God is within you. (Luke 17:21.)
