1. have always found their satisfaction in that Divine utterance, which our ears heard recited from the Gospel at the moment when that Power, which is its attestation, was bestowed upon us:—Go now and teach all nations, baptizing them in the Name of the Father, and of the Son, and of the Holy Ghost, teaching them to observe all things whatsoever I command you; and, lo, I am with you alway, even unto the end of the world. What element in the mystery of man’s salvation is not included in those words? What is forgotten, what left in darkness? All is full, as from the Divine fulness; perfect, as from the Divine perfection. The passage contains the exact words to be used, the essential acts, the sequence of processes, an insight into the Divine nature. He bade them baptize in the Name of the Father, and of the Son, and of the Holy Ghost, that is with confession of the Creator and of the Only-begotten, and of the Gift. For God the Father is One, from Whom are all things; and our Lord Jesus Christ the Only-begotten, through Whom are all things, is One; and the Spirit, God’s Gift to us, Who pervades all things, is also One. Thus all are ranged according to powers possessed and benefits conferred;—the One Power from Whom all, the One Offspring through Whom all, the One Gift Who gives us perfect hope. Nothing can be found lacking in that supreme Union which embraces, in Father, Son and Holy Spirit, infinity in the Eternal, His Likeness in His express Image, our enjoyment of Him in the Gift.

2. But the errors of heretics and blasphemers force us to deal with unlawful matters, to scale perilous heights, to speak unutterable words, to trespass on forbidden ground. Faith ought in silence to fulfil the commandments, worshipping the Father, reverencing with Him the Son, abounding in the Holy Ghost, but we must strain the poor resources of our language to express thoughts too great for words. The error of others compels us to err in daring to embody in human terms truths which ought to be hidden in the silent veneration of the heart.

3. For there have risen many who have given to the plain words of Holy Writ some arbitrary interpretation of their own, instead of its true and only sense, and this in defiance of the clear meaning of words. Heresy lies in the sense assigned, not in the word written; the guilt is that of the expositor, not of the text. Is not truth indestructible? When we hear the name Father, is not sonship involved in that Name? The Holy Ghost is mentioned by name; must He not exist? We can no more separate fatherhood from the Father or sonship from the Son than we can deny the existence in the Holy Ghost of that gift which we receive. Yet men of distorted mind plunge the whole matter in doubt and difficulty, fatuously reversing the clear meaning of words, and depriving the Father of His fatherhood because they wish to strip the Son of His sonship. They take away the fatherhood by asserting that the Son is not a Son by nature; for a son is not of the nature of his father when begetter and begotten have not the same properties, and he is no son whose being is different from that of the father, and unlike it. Yet in what sense is God a Father (as He is), if He have not begotten in His Son that same substance and nature which are His own?
