Bede the Venerable
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.
After the account of the sisters, who signified the two lives of the Church, our Lord is not without reason related to have both Himself prayed, and taught His disciples to pray, seeing that the prayer which He taught contains in itself the mystery of each life, and the perfection of the lives themselves is to be obtained not by our own strength, but by prayer. Hence it is said, And it came to pass, that, as he was praying in a certain place.
