At every baptism the whole congregation reaffirms its faith in God and pledges itself to provide an environment of witness and service. Baptism should, therefore, always be celebrated and developed in the setting of the Christian community. Baptism is an unrepeatable act. Similarly, participation in Christ's death and resurrection is inseparably linked with the receiving of the Spirit. Baptism in its full meaning signifies and effects both.
Christian baptism takes place through water and the Holy Spirit.
If baptism, as incorporation into the Body of Christ, points by its very nature to the eucharistic sharing of Christ's body and blood, the question arises as to how a further and separate rite can be interposed between baptism and admission to communion. Baptism needs to be constantly reaffirmed. The most obvious form of such reaffirmation is the celebration of the eucharist. The renewal of baptismal vows may also take place during such occasions as the baptism of others. Mutual recognition of baptism is acknowledged as an important sign and means of expressing the baptismal unity given in Christ.
