Orthodox Christians, through baptism, enter a new life of salvation through repentance whose purpose is to share in the life of God through the work of the Holy Spirit.

The Eastern Orthodox believe that Christ, from the moment of his conception, was both fully God and fully human. Mary is thus called the Theotokos or Bogoroditsa as an affirmation of the divinity of the one to whom she
