The only ones who aren’t capable of evil are God the father, Christ the Word, and his Holy Spirit. God is the source of all goodness. Christ is the living form of Wisdom itself, and Wisdom cannot become foolishness. Christ is Righteousness, and Righteousness cannot become unrighteousness. He is the Word, which cannot become irrational; He is Light, which darkness cannot overcome. His Spirit is holy by its very nature, not merely by practicing holiness—holiness is inseparably built into his very nature, and he cannot be made somehow less holy.
