III. The Holy Spirit and the Church in the Liturgy

From The Catechism of the Catholic Church

1098
The assembly should prepare itself to encounter its Lord and to become “a
people well disposed.” the preparation of hearts is the joint work of the
Holy Spirit and the assembly, especially of its ministers. the grace of the
Holy Spirit seeks to awaken faith, conversion of heart, and adherence to the
Father’s will. These dispositions are the precondition both for the reception
of other graces conferred in the celebration itself and the fruits of new life
which the celebration is intended to produce afterward.
