Holy water is placed at the doors of Catholic Churches to remind us of the waters of Baptism which once flowed over our foreheads, to signify that we are not worthy to enter into the Presence of Christ without purification, and to forgive us those venial sins for which we are sorry, as well as remitting the temporal punishment due to our sins according to the measure of our regret and contrition. I do not know how you feel, but I know that I am not worthy to enter into the Presence of God in a Catholic Church. When Moses approached the burning bush, God said to him, “Come not hither. Put off the shoes from thy feet, for the place whereon thou standest is holy ground.” To Catholics it is a joy to be able to make straight for the holy water font on entering into the Presence of God in the Blessed Sacrament, and to make use of those waters of purification, asking God to make them a little more fit to appear before Him.
