Augustine of Hippo
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.
(in Enchirid. c. 116.) It seems according to the Evangelist Matthew, that the Lord’s prayer contains seven petitions, but Luke has comprehended it in five. Nor in truth does the one disagree from the other, but the latter has suggested by his brevity how those seven are to be understood. For the name of God is hallowed in the spirit, but the kingdom of God is about to come at the resurrection of the body. Luke then, shewing that the third petition is in a manner a repetition of the two former, wished to make it so understood by omitting it. He then added three others. And first, of daily bread, saying, Give us day by day our daily bread.
