The word "Procession" is used to express the relation in the Blessed Trinity between the Father and the Holy Ghost. As we believe that the Son is eternally begotten of the Father, so we believe that the Holy Ghost is a Person eternally proceeding from the Father, as set forth in the article of the Creed, "Who proceedeth from the Father and the Son." The words "and the Son" were added later, and the article is generally interpreted as meaning that the Holy Ghost emanates from the Father through the Son, and therefore proceeds from both; or as an ancient writer expressed it, "Always hath the Spirit proceeded from the Father and received of the Son." (See HOLY GHOST, also FILIOQUE.)
