How is it possible to believe in the Old Testament in which there is just one God and at the same time believe in Trinity?
If the concept of Trinity is difficult to understand and a mystery, why is it such an important doctrine in Christianity?
The doctrine of the Trinity is essential to Christianity because it helps Christians understand the nature of God and how he has revealed himself to humanity. The Father, Son, and Holy Spirit are all described as divine in the New Testament, and they all work together to accomplish God's purposes. So, while the Trinity may be difficult to understand, it is an essential part of Christian belief.
