St. Cyprian on the "Our Father"

From the writings of St. Cyprian in today's Office of Readings in the Liturgy of the Hours:

"So, my brothers, let us pray as God our master has taught us. To ask the Father in words his Son has given us, to let him hear the prayer of Christ ringing in his ears, is to make our prayer one of friendship, a family prayer. Let the Father recognize the words of his Son. Let the Son who lives in our hearts be also on our lips. We have him as an advocate for sinners before the Father; when we ask forgiveness for our sins, let us use the words given by our advocate. He tells us, Whatever you ask the Father in my name, he will give you. What more effective prayer could we then make in the name of Christ than in the words of his own prayer?"
