The Holy Spirit, since He sanctifies creatures, is neither a creature nor subject to change. He is always good, since He is given by the Father and the Son; neither is He to be numbered amongst such things as are said to fail. He must be acknowledged as the source of goodness. The Spirit of God’s mouth, the amender of evils, and Himself good. Lastly, as He is said in Scripture to be good, and is joined to the Father and the Son in baptism, He cannot possibly be denied to be good. He is not, however, said to progress, but to be made perfect in goodness, which distinguishes Him from all creatures.
