We need not be surprised, my dear brethren, at the honor which the Church pays to this holy wood, which obtains for us so many graces and so many benefits. We see that the Church makes the Sign of the Cross in all her ceremonies, in the administration of all the Sacraments. Why is that? My friends, this is why. It is because all our prayers and all the Sacraments draw from the Cross their power and their virtue. During the Holy Sacrifice of the Mass, which is the greatest, the most solemn and the most sublime of all those actions which can glorify God, the priest makes the Sign of the Cross over and over again. God desires that we may never lose the memory of it as the surest means of our salvation and the most formidable instrument for repelling the Devil. He has created us in the form of a cross so that every man might be the image of this cross upon which Jesus Christ died to save us. See how eager the Church is to increase their number? She urges them as a special embellishment on our churches and on all altars; she places them in the most public places.
–Saint John Vianney (1786-1859)
