Moreover, those phantoms which Servetus substitutes for the hypostases he so transforms as to make new changes in God. But the most execrable heresy of all is his confounding both the Son and Spirit promiscuously with all the creatures. For he distinctly asserts, that there are parts and partitions in the essence of God, and that every such portion is God. This he does especially when he says, that the spirits of the faithful are co-eternal and consubstantial with God, although he elsewhere assigns a substantial divinity, not only to the soul of man, but to all created things.
