Chapter 10 — Part I: The Creed — Article VIII: I Believe in the Holy Ghost
Section 18. To say nothing of other testimonies of Scripture, the form of Baptism, taught by our Redeemer,' shows most clearly that the Holy Ghost is the Third Person, self-existent in the Divine Nature and distinct from the other Persons. It is a doctrine taught also by the Apostle when he says: The grace of our Lord Jesus Christ, and the charity of God, and the communication of the Holy Ghost, be with you all. Amen.
