“God is One, but He is also three—the Father, Son, and Spirit. Each is fully and equally God, yet each Person is distinct from one another. The Father is God, the Son is God, and the Spirit is God. But the Father is not the Son nor the Spirit, the Son is not the Father nor the Spirit, and the Spirit is not the Father nor the Son.”
--Aaron Armstrong (Devotional Doctrine, p. 33)
