Council of Toledo XVI, 693

cause so perfect is His nature, that this being is to Him as willing, as understanding. . . .

295. Passing also to a re-examination of the second chapter in which the same Pope thought that we had incautiously said that three substances are professed in Christ, the Son of God, as we will not be ashamed to defend the things that are true, so perchance others will be ashamed to be ignorant of the things that are true. For who does not know that every man consists of two substances, namely of the soul and of the body? . . . Therefore when the divine nature has been joined to the human nature, they can be called both three personal and two personal substances. . . .

Profession of Faith concerning the Trinity ¹

296. Let the designation of this "holy will"—although through a comparative similitude of the Trinity, where it is called memory, intelligence, and will—refer to the person of the Holy Spirit; according to this, however, what applies to itself, is predicated substantially. For the will is the Father, the will is the Son, the will is the Holy Spirit; and many other similar things, according to substance, which those who live as protectors of the Catholic faith do not for any reason hesitate to say. And just as it is Catholic to say: God from God, light from light, life from life, so it is a proved assertion of true faith to say the will from the will; just as wisdom from wisdom, essence from essence, and as God the Father begot God the Son, so the Will, the Father, begot the Son, the Will. Thus, although according to essence the Father is will, the Son is will and the Holy Spirit is will, we must not however believe that there is unity according to a relative sense, since one is the Father who refers to the Son, another the Son, who refers to the Father, another the Holy Spirit who, because He proceeds from the Father and the Son, refers to the Father and the Son; not the same but one in one way, one in another, because to whom there is one being in the nature of deity, to these there is a special property in the distinction of persons.
