xii. As soon as it was introduced into the Churches of the West it brought forth disgraceful fruits, bringing with it, little by little, other novelties, for the most part contrary to the express commands of our Savior in the Gospel—commands which till its entrance into the Churches were closely observed. Among these novelties may be numbered sprinkling instead of baptism, denial of the divine Cup to the Laity, elevation of one and the same bread broken, the use of wafers, unleavened instead of real bread, the disuse of the Benediction in the Liturgies, even of the sacred Invocation of the All-holy and Consecrating Spirit, the abandonment of the old Apostolic Mysteries of the Church, such as not anointing baptized infants, or their not receiving the Eucharist, the exclusion of married men from the Priesthood, the infallibility of the Pope and his claim as Vicar of Christ, and the like. Thus it was that the interpolation led to the setting aside of the old Apostolic pattern of well nigh all the Mysteries and all doctrine, a pattern which the ancient, holy, and orthodox Church of Rome kept, when she was the most honored part of the Holy, Catholic and Apostolic Church.
xiii. It drove the theologians of the West, as its defenders, since they had no ground either in Scripture or the Fathers to countenance heretical teachings, not only into misrepresentations of the Scriptures, such as are seen in none of the Fathers of the Holy Catholic Church, but also into adulterations of the sacred and pure writings of the Fathers alike of the East and West.
xiv. It seemed strange, unheard of, and blasphemous, even to those reputed Christian communions, which, before its origin, had been for other just causes for ages cut off from the Catholic fold.
xv. It has not yet been even plausibly defended out of the Scriptures, or with the least reason out of the Fathers, from the accusations brought against it, notwithstanding all the zeal and efforts of its supporters. The doctrine bears all the marks of error arising out of its nature and peculiarities. All erroneous doctrine touching the Catholic truth of the Blessed Trinity, and the origin of the divine Persons, and the subsistence of the Holy Ghost, is and is called heresy, and they who so hold are deemed heretics, according to the sentence of St. Damasus, Pope of Rome, who says: “If any one rightly holds concerning the Father and the Son, yet holds not rightly of the Holy Ghost, he is an heretic” (Cath. Conf. of Faith which Pope Damasus sent to Paulinus, Bishop of Thessalonica). Wherefore the One, Holy, Catholic, and Apostolic Church, following in the steps of the holy Fathers, both Eastern and Western, proclaimed of old to our progenitors and again teaches today synodically, that the said novel doctrine of the Holy Ghost proceeding from the Father and the Son is essentially heresy, and its maintainers, whoever they be, are heretics, according to the sentence of Pope St. Damasus, and that the congregations of such are also heretical, and that all spiritual communion in worship of the orthodox sons of the Catholic Church with such is unlawful. Such is the force of the seventh Canon of the third Ecumenical Council.
