 We assuredly see the sign of a cross, naturally, in the ship when it is carried along with swelling sails, when it glides forward with expanded oars; and when the military yoke is lifted up, it is the sign of a cross; and when a man adores God with a pure mind, with hands outstretched.Thus the sign of the cross either is sustained by a natural reason, or your own religion is formed with respect to it.
