God does not have three wills , and yet each divine person has His own will. God is nowise made of body ,nor does He underlie accidents. Lastly God is at once the Father the Son and the Holy Spirit. By way of substance, which is manifestly expressed by way of hypostases. One is the Father another is the Son and another is the Holy Spirit. Thus we say three persons, but not as if there exist any real composition or subjection.
