On the basis of age-old custom, water is one of the signs that the Church often uses in blessing the faithful. Holy water reminds the faithful of Christ, who is given to us as the supreme divine blessing, who called himself the living water, and who, with water, established Baptism for our sake as the sacramental sign of the blessing that brings salvation....However... The Bible nowhere instructs Christians to use "holy water" in any way, shape, or form. The Catholic use of holy water is not biblical...BUT that does not mean that its witchcraft....
