Catena Aurea · Lukasevangelium 22
And he came out, and went, as he was wont, to the mount of Olives; and his disciples also followed him. And when he was at the place, he said unto them, Pray that ye enter not into temptation. And he was withdrawn from them about a stone’s cast, and kneeled down, and prayed, Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done.
But what meaneth His bending of knees? of which it is said, And he kneeled down, and prayed. It is the way of men to pray to their superiors with their faces on the ground, testifying by the action that the greater of the two are those who are asked. Now it is plain that human nature contains nothing worthy of God’s imitation. Accordingly the tokens of respect which we evince to one another, confessing ourselves to be inferior to our neighbours, we have transferred to the humiliation of the Incomparable Nature. And thus He who bore our sicknesses and interceded for us, bent His knee in prayer, by reason of the man which He assumed, giving us an example, that we ought not to exalt ourselves at the time of prayer, but in all things be conformed to humility; for God resisteth the proud, but giveth grace to the humble. (James 4:6, 1 Pet. 5:5.)
