By laudable custom, each time we enter a church building we take holy water from a place by the door and with it trace upon our bodies the sign of the life-giving cross. Two things are significant about this outwardly simple gesture. First, we do it to remind ourselves of the saving power of that cross; of the effects of the sacrifice of Christ on that cross which, through baptism—our own ritual cleansing with water—we have now inherited. Secondly, we make this act of reverence as we come into the church from the world. We move to the sacred from the profane, literally turning our backs on the world and orienting ourselves toward the dwelling-place of the Lord our God.
