the Son in all things, and that the Father alone is infinite and eternal, and that the Logos is God's true firstborn and subservient Son who was made perfect flesh for our sakes and for the glory of the Father (this confession was later known as the Blasphemy of Sirmium): "But since many persons are disturbed by questions concerning what is called in Latin substantia, but in Greek ousia, that is, to make it understood more exactly, as to 'coessential,' or what is called, 'like-in-essence,' there ought to be no mention of any of these at all, nor exposition of them in the Church, for this reason and for this consideration, that in divine Scripture nothing is written about them, and that they are above men's knowledge and above men's understanding"; Psilanthropism – Ebionites (1st to 4th centuries AD) observed Jewish law, denied the literal virgin birth and regarded Jesus as the Jewish Messiah and the greatest prophet of God only; Socinianism – Photinus taught that Jesus was the sinless Messiah and redeemer, and the only perfect human son of God, but that he had no pre-human existence. They interpret verses such as John 1:1 to refer to God's "plan" existing in God's mind before Christ's birth, and that it was God's plan that "became flesh", as the perfect man Jesus; Unitarianism views Jesus as the son of God, subordinate and distinct from his Father; Many Gnostic traditions held that the Christ is a heavenly Aeon but not one with the Father. Those who believe that the Father, the resurrected Son and the Holy Spirit are different aspects of one God, as perceived by the believer, rather than three distinct persons: Modalism – Sabellius (fl. c.215) stated that God took numerous forms in both the Hebrew and the Christian Greek Scriptures, and that God has manifested himself in three primary modes regarding the salvation of mankind. He contended that "Father, Son, and Spirit" were different roles played by the same divine person in various circumstances in history; thus God is Father in creation (God created a Son through the virgin birth), Son in redemption (God manifested himself as Jesus for the purpose of his death upon the cross), and Holy Spirit in regeneration (God's Spirit within the Son and within the souls of Christian believers). In this view, God is not three distinct persons, but rather one person manifesting himself
