paragraph_text: Trinity
  
  Trinity refers to the teaching that the one God comprises three distinct, eternally co-existing persons: the Father, the Son (incarnate in Jesus Christ) and the Holy Spirit. Together, these three persons are sometimes called the Godhead, although there is no single term in use in Scripture to denote the unified Godhead. In the words of the Athanasian Creed, an early statement of Christian belief, "the Father is God, the Son is God, and the Holy Spirit is God, and yet there are not three Gods but one God". They are distinct from another: the Father has no source, the Son is begotten of the Father, and the Spirit proceeds from the Father. Though distinct, the three persons cannot be divided from one another in being or in operation. While some Christians also believe that God appeared as the Father in the Old Testament, it is agreed that he appeared as the Son in the New Testament and will still continue to manifest as the Holy Spirit in the present. But still, God still existed as three persons in each of these times. However, traditionally there is a belief that it was the Son who appeared in the Old Testament because, for example, when the Trinity is depicted in art, the Son typically has the distinctive appearance, a cruciform halo identifying Christ, and in depictions of the Garden of Eden, this looks forward to an Incarnation yet to occur. In some Early Christian sarcophagi, the Logos is distinguished with a beard, "which allows him to appear ancient, even pre-existent".
  
  The Trinity is an essential doctrine of mainstream Christianity. From earlier than the times of the Nicene Creed (325) Christianity advocated the triune mystery -nature of God as a normative profession of faith. According to Roger E. Olson and Christopher Hall, through prayer, meditation, study and practice, the Christian community concluded "that God must exist as both a unity and trinity", codifying this in ecumenical council at the end of the 4th century.
  
  According to this doctrine, God is not divided in the sense that each person has a third of the whole; rather, each person is considered to be fully God (see Perichoresis). The distinction lies in their relations, the Father being unbegotten; the Son being begotten of the Father; and the Holy Spirit proceeding from the Father and (in Western Christian theology) from the Son. Regardless of this apparent difference, the three "persons" are each eternal and omnipotent. Other Christian religions including Unitarian Universalism, Jehovah's Witnesses, and Mormonism, do not share those views on the Trinity.
  
  The Greek word trias is first seen in this sense in the works of Theophilus of Antioch; his text reads: "of the Trinity, of God, and of His Word, and of His Wisdom". The term may have been in use before this time; its Latin equivalent, trinitas, appears afterwards with an explicit reference to the Father, the Son, and the Holy Spirit, in Tertullian. In the following century, the word was in general use. It is found in many passages of Origen.
