The mystery of Baptism is the door into the Church, the Kingdom of grace. It is with Baptism that Christian life begins. Baptism is the frontier that separates the members of Christ’s Body from those who are outside it. In Baptism the human person is arrayed in Christ, following the words of St. Paul which are sung as the newly-baptized is led around the baptismal font: For as many of you who were baptized into Christ have put on Christ’ (Gal.3:27). In Baptism the human person dies to his sinful life and rises again to new spiritual life.

The sacrament of Baptism was instituted by Christ Himself: ‘Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit’ (Matt 28:19). Christ’s commandment already contains the basic elements of the baptismal rite: preliminary teaching (‘catechization’), without which the adoption of faith cannot be conscious; immersion in water (Greek baptismos, literally ‘immersion’); and the formula ‘in the name of the Father and of the Son and of the Holy Spirit’. In the early Church Baptism was accomplished through complete immersion in water. However, at an early date special pools (baptisteries) were built and into these the candidates for baptism were plunged. The practice of pouring water over the person or sprinkling him with water existed in the early Church, though not quite as a norm.

At the time of Constantine (fourth century) adult baptism was more common than the baptism of infants, the emphasis being laid on the conscious acceptance of the sacrament. Some postponed the sacrament until the end of their life in the knowledge that sins were forgiven in Baptism. The Emperor Constantine was baptized just before his death. St. Gregory the Theologian, a son of a bishop, was baptized only when he reached maturity. Saints Basil the Great and John Chrysostom were baptized only after completing their higher education.

However, the practice of baptizing infants is no less ancient — the apostles baptized whole families which might well have included children (cf/ Acts 10:48). St. Irenaeus of Lyons (second century) says: ‘Christ came to save those who through Him are reborn into God: infants, children, adolescents and the elderly’. Origen in the third century calls the custom of baptizing infants an ‘apostolic tradition’. The local Council of Carthage (third century) pronounced an anathema upon those who rejected the necessity of baptizing infants and newly-born children.

The sacrament of Baptism, like all other sacraments, must be received consciously. Christian faith is the prerequisite for the validity of the sacrament. If an infant is baptized, the confession of faith is solemnly pronounced by his godparents, who thereby are obliged to bring the child up in the faith and make his Baptism conscious. An infant who receives the sacrament cannot rationally understand what is happening to him, yet his soul is fully capable of receiving the grace of the Holy Spirit. ‘I believe’, writes St. Symeon the New Theologian, ‘that baptized infants are sanctified and are preserved under the wing of the All-Holy Spirit and that they are lambs of the spiritual flock of Christ and chosen lambs, for they have been imprinted with the sign of the life-giving Cross and freed completely from the tyranny of the devil’. The grace of God is given to infants as a pledge of their future belief, as a seed cast into the earth: for the seed to grow into a tree and bring forth fruit, the efforts both of the godparents and of the one baptized as he grows are needed.

Immediately after Baptism or in the days that follow, the newly-baptized, irrespective of age, receives Holy Communion. In the Roman Catholic Church Chrismation (Confirmation) and First Communion take place after the child has reached the age of seven, but the Orthodox Church admits children to these sacraments as early as possible. The understanding behind this practice is that children ought not to be deprived of a living, even if not a fully conscious, contact with Christ.

The sacrament of Baptism occurs only once in a person’s life. In Baptism the human person is granted freedom from original sin and forgiveness of all his personal transgressions. However, Baptism is only the first step in the human person’s ascent towards God. If it is not accompanied by a renewal of one’s entire life and a spiritual regeneration, it might be fruitless. The grace of God, received in Baptism as a pledge or as a seed, will grow within the person and be made manifest throughout his whole life so long as he strives towards Christ, lives in the Church and fulfills God’s commandments.
