The Protestant Churches, including Presbyterian, believe there are only 2 Holy Sacraments sanctioned by the Ministry of Jesus: Baptism and Holy Communion. "There are two Sacraments ordained of Christ our Lord in the Gospel, that is to say, Baptism and the Supper of the Lord."
Baptism usually occurs during infancy, though a person may be baptized at any age. Parents bring their baby to church, where they publicly declare their desire that he or she be baptized. When an infant or child is baptized the Church commits itself to nurture the child in faith. When adults are baptized they make a public profession of faith.
Confirmation is a personal affirmation of the baptism vows made on behalf of persons by their parents or caregivers and the church and a personal profession of faith in Jesus Christ. Those confirmed must be 12 or older.
