Blessing of the Waters in Clearwater
The use of holy water is based on the Baptism of Jesus by John the Baptist in the River Jordan. John's baptism was a baptism of repentance, and the people came to have their sins washed away by the water. Since Jesus had no sin, but was God incarnate, his baptism had the effect not of washing away Jesus' sins, but of blessing the water, making it holy—and with it all of creation, so that it may be used fully for its original created purpose to be an instrument of life. Blessing of the water at St. George church. Everyone was given the Holy water to drink and to take home.
