Sermons on Selected Lessons of the New Testament

³⁶ But in this passage according to Matthew, the Lord far more plainly explained what he intended to be understood here; namely, that he it is who speaks a word against the Holy Ghost, who with an impenitent heart resists the Unity of the Church, where in the Holy Spirit is given the remission of sins. For this spirit they have not, as has been said already, who even though they bear and handle the sacraments of Christ, are separated from His congregation. For when He spoke of the division of Satan against Satan, and how that He Himself cast out devils by the Holy Spirit, that Spirit, namely, which is not, as the other, divided against Himself; lest any one should think because of those who gather together their irregular assemblies under the Name of Christ, but without His fold, that the kingdom of Christ also was divided against itself, He immediately added, “He that is not with Me is against Me, and he that gathers not with Me scatters abroad,” that He might show that they did not belong to Him who by gathering “without” wished not to “gather” but “to scatter abroad.”

And afterwards He subjoined, “Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men; but the blasphemy of the Spirit shall not be forgiven.” What is this “wherefore?” Shall the blasphemy of the Spirit only not be forgiven, because “he who is not with Christ is against Him, and he who gathers not with Him scatters abroad?” Even so, doubtless. For he that gathers not with Him, howsoever he may gather under His name, has not the Holy Ghost.
