With the worst kind of death, that is, crucifixion, they long to murder the innocent. For they who hung on the cross, with their hands and feet fixed by nails to the wood, suffered a prolonged death, that their agony might not quickly cease; but the death of the cross was chosen by our Lord, as that which having overcome the Devil, He was about to place as a trophy on the brows of the faithful. – St. Bede
Then he makes the sign of the cross with his thumb, on the child’s forehead and breast.
Receive the sign of the Cross both upon thy forehead † and also upon thy heart † ; Embrace the faith with it’s divine precepts; and so live as to be, from henceforth, the temple of God. – Roman Rite of Baptism
