Why do we use water to bless ourselves when we enter Church and to sprinkle in our homes, cars, places of business, etc.? We know that we need to use water for baptisms, but how did the Church start using separate, blessed holy water for these other things? After all, in the earliest times of the Church baptisms took place in rivers, streams, and lakes, so they didn’t have baptismal fonts full of holy water in their churches. In fact, since Christianity was illegal, they didn’t even have churches in most places.
The Church probably used holy water from the earliest days since water was used in Jewish homes for purification, and the earliest Christians were mostly Jews. However, the earliest recorded use of holy water is from the fourth century. It’s a blessing of water to protect from disease, evil spirits, and all maladies. As soon as Christianity was legalized, churches began keeping the water from baptisms for people to use throughout the year. In the seventh century we begin to have records of churches keeping water at the entrance of the Church for people to bless themselves with or to take home with them.
Today, we use holy water for basically the same reasons. We bless ourselves, our homes, and our religious articles with holy water to ask God to purify them, to protect them from demonic influence, and to bestow His grace on them. When we bless ourselves with holy water whenever we enter Church, we’re doing at least two things. First, we’re reminding ourselves of our baptism, through which we first entered the Church and became children of God. Second, we’re asking God to purify us of sin and fill us with His grace. We recognize that we’re entering a holy place and ask God to make us worthy to enter his house.
Holy Water is a sacramental, not a sacrament. Sacraments, like baptism, work in and of themselves because of the power that God has given them. Sacramentals require the faith of the person using them to have an effect. If we just bless ourselves with holy water without really thinking about it, but just because that’s what we always do, then it’s not having much of an effect. So, every time you enter a Church and bless yourself with the holy water, ask God to stir up the graces of baptism in your soul, to forgive your sins, and to fill you with His lifegiving grace.
