The world-wide testimony of the Catholic Church is a sufficient witness to prove the coming of the Incarnate Son to redeem mankind, and to return to His Father; it is also sufficient to prove the advent of the Holy Ghost to abide with us for ever. The work of the Son in this world was accomplished by the Divine acts and facts of His three-and-thirty years of life, death, Resurrection, and Ascension. The office of the Holy Ghost is perpetual, not only as the Illuminator and Sanctifier of all who believe, but also as the Life and Guide of the Church. I may quote now the words of the Founder of the Church: "It is expedient to you that I go: for if I go not, the Paraclete will not come to you; but if I go, I will send Him to you."* "I will ask the Father, and He shall give you another Paraclete, that He may abide with you for ever."** "The Spirit of Truth, Whom the world cannot receive, because it seeth Him not nor knoweth Him; but you shall know Him, because He shall abide with you and shall be in you."*** * St. John, xvi. 7. ** Ibid, xiv. 16. *** St.John, xiv. 16, 17. St. Paul in the Epistles to the Ephesians describes the Church as a body of which the Head is in heaven, and the Author of its indefectible life abiding in it as His temple. Therefore the words, "He that heareth you heareth Me." This could not be if the witness of the Apostles had been only human. A Divine guidance was attached to the office they bore. They were, therefore, also judges of right and wrong, and teachers by Divine guidance of the truth. But the presence and guidance of the Spirit of Truth is as full at this day as when St. Irenæus wrote. As the Churches then were witnesses, judges, and teachers, so is the Church at this hour a world-wide witness, an unerring judge and teacher, divinely guided and guarded in the truth. It is therefore not only a human and historical, but a Divine witness. This is the chief Divine truth which the last three hundred years have obscured. Modern Christianity believes in the one advent of the Redeemer, but rejects the full and personal advent of the Holy Ghost. And yet the same evidence proves both. The Christianity of reformers, always returns to Judaism, because they reject the full, or do not believe the personal, advent of the Holy Ghost. They deny that there is an infallible teacher, among men; and therefore they return to the types and shadows of the Law before the Incarnation, when the Head was not yet incarnate, and the Body of Christ did not as yet exist.
