Augustine of Hippo

A sermon has to be preached about the evening sacrifice. We prayed after all as we sang, and we sang as we prayed, "May my prayer rise straight up like incense in your presence; the lifting up of my hands an evening sacrifice." In the prayer we observe the person, in the extension of the hands we recognize the cross. So this is the sign that we carry on our foreheads, the sign by which we have been saved. A sign that was mocked, in order to be honored; despised in order to be glorified. God appears in visible form, so that as man he may intercede; he remains hidden so that as man he may die. "For if they had known, they would never have crucified the Lord of glory." So this sacrifice, in which the priest is also the victim, has redeemed us by the shedding of the Creator's blood.
