Nicetas of Remesiana

The sin of one who blasphemes against the Holy Spirit is unpardonable. Compare with this judgment what is said in the book of Kings [Samuel]: “If one man shall sin against the Lord, who shall pray for him?” Thus, it is one and the same sin whether we blaspheme against the Holy Spirit or against God, and it is inexpiable. Hence, the nature of the Holy Spirit begins to dawn in our minds.

After this, you will find plenty of men and women, filled with a divine spirit, who sang of the mysteries of God. Among these was David. As a boy, he was given a special call to this office, and by God’s grace he became the prince of singers and left us a treasury of song. He was still a boy when his sweet, strong song with his harp subdued the evil spirit working in Saul. Not that there was any kind of power in the harp, but, with its wooden frame and the strings stretched across, it was a symbol of the cross of Christ. It was the passion that was being sung, and it was this which subdued the spirit of the devil.
