The Coptic Church calls these four redemptive Mysteries because they touch the believer’s entrance, healing, and communion with Christ. Salvation is life in Christ, and these Mysteries give that life in the Church.
Born and sealed
Baptism is the beginning. The baptized person is born again by water and the Spirit, receives remission of sins, and enters the Church. Coptic sources call Baptism the door into the rest of the sacramental life.
Unless one is born of water and the Spirit, he cannot enter the kingdom of God.
Chrismation follows Baptism as the seal of the Holy Spirit. Through the holy Myron, the baptized person receives the gift and indwelling of the Spirit and is strengthened for life in Christ.
Restored and fed
Confession is the Mystery of restoration after sin. The Christian life includes repentance because the baptized still need healing, forgiveness, and reconciliation. Through repentance, confession, and absolution, the Church applies Christ’s mercy to the wounded soul.
The Eucharist is the Mystery of communion. The faithful receive the true Body and Blood of Christ, the food of eternal life and the center of the Church’s worship.
Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day.
One saving life
These four Mysteries should be read together. Baptism begins the life. Chrismation seals it. Confession restores it. The Eucharist nourishes it.
That is why the question is larger than a list of ceremonies. The four redemptive Mysteries show how Christ saves the whole person inside His Church: birth, Spirit, repentance, and communion.
