Unless one is born of water and the Spirit, he cannot enter the kingdom of God.
The family carries the child
Parents and godparents speak on behalf of the child and promise to raise the child in the faith. Ordinary life already works this way: children receive family, language, citizenship, love, and discipline before they can explain them. The Church gives life first, then teaches the child to live it.
The child is therefore received into a covenant life, not treated as a religious consumer waiting to decide whether grace is useful. The parents and godparents become responsible to teach prayer, fasting, repentance, Scripture, the sign of the Cross, and love for the Church as the child matures.
Baptism is followed by Myron and Communion
In Coptic practice, the newly baptized child is also anointed with the Holy Myron and brought into Eucharistic life. The sacraments are not treated as ideas to study from a distance. They are the life in which the child is formed.
This order matters. Baptism gives new birth, Myron seals the baptized with the gift of the Holy Spirit, and Communion nourishes the child with Christ’s Body and Blood. The Church does not separate children from the sacramental life while waiting for adult explanation.
Grace comes before explanation
Infant Baptism teaches that salvation is grace. The child is welcomed because Christ welcomes children, and the parish then takes seriously the responsibility to teach that child to pray, repent, confess Christ, and live as a member of His Body.
