Baptism is the “frontier” sacrament because it begins life in Christ. When a person is baptised, the Spirit creates a life in Christ that knows no end. This life is then sustained during one’s earthly pilgrimage through the hearing of God’s Word and receiving the Lord’s Supper. Baptism, that simple moment of water, Word & Spirit, is a rite of Christian initiation – by it we enter a new life and are separated from the life we lived before Christ.
For everybody, life is a journey from birth to death – but for Christians, life is a pilgrimage from baptism to death - which itself is the entrance into full communion with Christ. St Paul describes Baptism as a journey through death and burial with Christ to a resurrection into eternal life (Romans 6). In the waters of Baptism, the Christian gets death over with as he/she dies and is buried with Christ and is reborn to a new life in Christ that never ends. Because Jesus has gone through the cross and tomb, we now rest assured that our journey in Baptism with Him will result in the destiny Jesus intends for us all: life in a resurrected body that knows no end.
Along the way to full communion with Christ in heaven, Christians live under the cross where we are continually in Christ, hearing His Holy Word and feeding upon the holy food of His body and blood to sustain us on our journey. Our pilgrimage reaches completion just beyond the portal of physical death, which is a portal through which we pass into full communion with Christ in His heavenly home. The goal of our journey is to live in Christ’s presence forever and to feast at His table for eternity.
The Christian life/pilgrimage is therefore a journey from Baptism to the Lord’s Supper. As we journey from our second birth (Baptism) toward the heavenly wedding feast (Revelation 19:6-9), of which the Lord’s Supper is a foretaste, we listen to Jesus (preaching) & so receive fuller instructing about the mysteries of Baptism & participation in the eternal heavenly feast.
