Catechism of the Catholic Church

The traditional form of petition to the Holy Spirit is to invoke the Father through Christ our Lord to give us the Consoler Spirit. Jesus insists on this petition to be made in his name at the very moment when he promises the gift of the Spirit of Truth. But the simplest and most direct prayer is also traditional, "Come, Holy Spirit," and every liturgical tradition has developed it in antiphons and hymns. > Come, Holy Spirit, fill the hearts of your faithful and enkindle in them the fire of your love. > Heavenly King, Consoler Spirit, Spirit of Truth, present everywhere and filling all things, treasure of all good and source of all life, come dwell in us, cleanse and save us, you who are All-Good.
