CCC 1298 When Confirmation is celebrated separately from Baptism, as is the case in the Roman Rite, the Liturgy of Confirmation begins with the renewal of baptismal promises and the profession of faith by the confirmands. This clearly shows that Confirmation follows Baptism.1 When adults are baptized, they immediately receive Confirmation and participate in the Eucharist.2

CCC 1299 In the Roman Rite the bishop extends his hands over the whole group of the confirmands. Since the time of the apostles this gesture has signified the gift of the Spirit. The bishop invokes the outpouring of the Spirit in these words:
All-powerful God, Father of our Lord Jesus Christ,
by water and the Holy Spirit
you freed your sons and daughters from sin
and gave them new life.
Send your Holy Spirit upon them
to be their helper and guide.
Give them the spirit of wisdom and understanding,
the spirit of right judgment and courage,
the spirit of knowledge and reverence.
Fill them with the spirit of wonder and awe in your presence.
We ask this through Christ our Lord.3
