III. The Holy Spirit and the Church in the Liturgy

From The Catechism of the Catholic Church

1105
The Epiclesis (“invocation upon”) is the intercession in which the
priest begs the Father to send the Holy Spirit, the Sanctifier, so that the
offerings may become the body and blood of Christ and that the faithful by
receiving them, may themselves become a living offering to God.²³
