Holy Baptism is the first of seven Sacraments in the Orthodox Christian
Church. Together with the Sacrament of Holy Chrism it joins the candidate
to the Mystical Body of Christ, the Church.

It was the Lord Jesus who instituted Baptism. "He who believes and is
baptised will be saved" (Mark 16:16). "Go therefore and make disciples of all
nations, baptising them in the name of the Father and of the Son and of the
Holy Spirit..." (Matthew 28:19).

"Truly, I say to you, unless one is born of water and the Spirit, he cannot
enter the kingdom of God" (John 3:5). The great model of our baptism, then,
is the baptism of Jesus in the River Jordan.

Baptism also removes the consequences of the 'original sin'. It also opens the
door of salvation and eternal life to him or her.
