  Christianity is a monotheistic religion in which most mainstream congregations and denominations accept the concept of the Holy Trinity. Modern orthodox Christians believe that the Trinity is composed of three equal, cosubstantial persons: God the Father, God the Son, and the Holy Spirit. The first person to describe the persons of the Trinity as homooúsios (ὁμοούσιος; "of the same substance") was the Church Father Origen. Although most early Christian theologians (including Origen) were Subordinationists, who believed that the Father was superior to the Son and the Son superior to the Holy Spirit, this belief was condemned as heretical by the First Council of Nicaea in the fourth century, which declared that all three persons of the Trinity are equal. Christians regard the universe as an element in God's actualization and the Holy Spirit is seen as the divine essence that is "the unity and relation of the Father and the Son". According to George Hunsinger, the doctrine of the Trinity justifies worship in a Church, wherein Jesus Christ is deemed to be a full deity with the Christian cross as his icon.
  
  The theological examination of Jesus Christ, of divine grace in incarnation, his non-transferability and completeness has been a historic topic. For example, the Council of Chalcedon in 451 CE declared that in "one person Jesus Christ, fullness of deity and fullness of humanity are united, the union of the natures being such that they can neither be divided nor confused". Jesus Christ, according to the New Testament, is the self-disclosure of the one, true God, both in his teaching and in his person; Christ, in Christian faith, is considered the incarnation of God.
