1 João 5:7
The Lord says, "I and the Father are one;" and again it is written of the Father, and of the Son, and of the Holy Spirit, "And these three are one." And does any one believe that this unity which thus comes from the divine strength and coheres in celestial sacraments, can be divided in the Church, and can be separated by the parting asunder of opposing wills? He who does not hold this unity does not hold God's law, does not hold the faith of the Father and the Son, does not hold life and salvation. — Treatise 1. On the Unity of the Church
1 João 5:16
That remission cannot in the Church be granted unto him who has sinned against God (i.e., the Holy Ghost): In the Gospel according to Matthew: "Whosoever shall say a word against the Son of man, it shall be forgiven him; but whosoever shall speak against the Holy Ghost, it shall not be forgiven him, neither in this world nor in the world to come." Also according to Mark: "All sins shall be forgiven, and blasphemies, to the sons of men; but whoever shall blaspheme against the Holy Ghost, it shall not be forgiven him, but he shall be guilty of eternal sin." Of this same thing in the first book of Kings: "If a man sin by offending against a man, they shall pray the Lord for him; but if a man sin against God, who shall pray for him?" — Treatise XII Three Books of Testimonies Against the Jews
