Catechism of the Catholic Church
692 When he proclaims and promises the coming of the Holy Spirit, Jesus calls him the "Paraclete," literally, "he who is called to one's side," ad-vocatus. 18 "Paraclete" is commonly translated by "consoler," and Jesus is the first consoler. 19 The Lord also called the Holy Spirit "the Spirit of truth." 20
693 Besides the proper name of "Holy Spirit," which is most frequently used in the Acts of the Apostles and in the Epistles, we also find in St. Paul the titles: the Spirit of the promise, 21 the Spirit of adoption, 22 the Spirit of Christ, 23 the Spirit of the Lord, 24 and the Spirit of God 25 - and, in St. Peter, the Spirit of glory. 26
