Kolminaisuus

Kolminaisuus is a concept in Christian theology that refers to the doctrine of the Holy Trinity. It asserts that God is one being in three persons: the Father, the Son (Jesus Christ), and the Holy Spirit. This doctrine is central to the Nicene Creed, which states, "We believe in one God, the Father Almighty, maker of heaven and earth, and of all things visible and invisible. And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds, God of God, Light of Light, very God of very God, begotten, not made, being of one substance with the Father; by whom all things were made. For us men and for our salvation he came down from heaven, and was incarnate by the Holy Spirit of the Virgin Mary, and was made man. For our sake he was crucified under Pontius Pilate, he suffered and was buried, and rose again on the third day in accordance with the Scriptures. He ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and his kingdom will have no end."

The doctrine of the Holy Trinity is a complex theological concept that has been debated and refined over centuries. It is a central tenet of mainstream Christian faiths, including Catholicism, Orthodoxy, and Protestantism. The Trinity is often illustrated through various symbols and metaphors, such as the triangle, the circle, and the flame, to represent the unity and diversity of the three persons within the one God. Despite its complexity, the doctrine of the Holy Trinity is a foundational belief for many Christians, emphasizing the unity and diversity within the divine nature.
