Mainstream Christianity, encompassing Catholic, Orthodox, and most Protestant denominations, holds a Trinitarian view of Jesus. In this doctrine, Jesus is understood as the Second Person of the Holy Trinity, co-equal, co-eternal, and consubstantial with God the Father and God the Holy Spirit. He is fully God and fully human, a divine mystery affirmed by early ecumenical councils, such as the Council of Nicaea in 325 CE. From this perspective, Jesus is not a created being but eternally begotten of the Father. His divine nature is essential for his atoning sacrifice to be effective for all humanity, as only God could bridge the infinite gap between humanity and a holy God.
