Why is the concept of TRINITY Christianity, so polytheistic in nature?
Trinitarianism is the belief that there are three persons in one God. This has been stated in various ways, such as “one God in three Persons” and “three persons in one substance.” It holds that in God are three distinctions of essence, not just of activity. The names given to these three persons are God the Father, God the Son, and God the Holy Ghost (or Holy Spirit). Orthodox trinitarians deny tritheism, which is the belief in three gods. However, when asked to explain how there can be three distinct persons and yet only one God, they ultimately explain that the trinity is a mystery our finite human minds cannot comprehend fully. It is apparent that many trinitarians interpret their doctrine to mean three personalities, three beings, three minds, three wills, or three bodies in the Godhead. They deny that by person they mean only manifestations, roles, or relationships with man. Instead, they defend an eternal threeness of essence while admitting it to be an incomprehensible mystery.
