Sermons on Selected Lessons of the New Testament

⁵ But these words of the Gospel, though they had some obscurity, which I think by the Lord's assistance I have explained, were yet not so difficult, as that which follows would seem to be. “Wherefore I say unto you, all manner of sin and blasphemy shall be forgiven unto men, but the blasphemy against the Spirit shall not be forgiven unto men. And whosoever speaks a word against the Son of Man, it shall be forgiven him; but whosoever speaks against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.” What then will become of those whom the Church desires to gain?

When they have been reformed and come into the Church from whatsoever error, is the hope in the remission of all sins that is promised them a false hope? For who is not convicted of having spoken a word against the Holy Ghost, before he became a Christian or a Catholic? In the first place, are not they who are called Pagans, the worshippers of many and false gods, and the adorers of idols, forasmuch as they say that the Lord Christ wrought miracles by magical arts, are not they like these who said that He cast out devils through the prince of the devils?

And again, when day by day they blaspheme our sanctification, what else blaspheme they but the Holy Ghost? What? Do not the Jews— they who spoke concerning our Lord what gave occasion to this very discourse— do they not even to the present day speak a word against the Holy Ghost, by denying that He is now in Christians, just as the others denied Him to be in Christ? For not even did they revile the Holy Ghost, by asserting either that He existed not, or that though He existed, yet that He was not God, but a creature; or that He had no power to cast out devils; they did not speak thus unworthily, or anything like it, of the Holy Ghost.

For the Sadducees indeed denied the Holy Ghost; but the Pharisees maintained His existence against their heresy, but they denied that He was in the Lord Jesus Christ, who they thought cast out devils through the prince of the devils, whereas He did cast them out through the Holy Ghost. And hence, both Jews and whatsoever heretics there are who confess the Holy Ghost, but deny that He is in the Body of Christ, which is His One Only Church, none other than the One Catholic Church, are without doubt like the Pharisees who at that time although they confessed the existence of the Holy Ghost, yet denied that He was in Christ, whose works in casting out devils they attributed to the prince of devils.

I say nothing of the fact that some heretics either boldly maintain that the Holy Ghost is not the Creator but a creature, as the Arians, and Eunomians, and Macedonians, or so entirely deny His existence, as to deny that God is Trinity, but assert that He is God the Father only, and that He is sometimes called the Son, and sometimes the Holy Ghost; as the Sabellians, whom some call Patripassians, because they hold that the Father suffered; and forasmuch as they deny that He has any Son, without doubt they deny His Holy Spirit also. The Photinians again who say that the Father only is God, and the Son a mere man, deny altogether that there is any third Person of the Holy Ghost.
