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?
But the Old Testament talks about only one God. How can three persons be one God?
That's a good point. The concept of Trinity is difficult to understand because it is a mystery, but it is a fundamental doctrine in Christianity. Some people understand the Trinity as three distinct persons who share one essence or substance, which is God. Others describe it as one God who expresses himself in different ways at different times.
