Chapter 3 — Part I — Article I (Of God the Father)

Section 95. Q. Are the three Hypostases or Persons of the Most Holy Trinity all of equal majesty? A. Yes; all of absolutely equal divine majesty. The Father is true God, the Son equally true God, and the Holy Ghost true God; but yet so that in the three Persons there is only one Tri-personal God.
