What is trinity definition?

The Trinity is a concept in Christian theology that refers to God as a triune entity consisting of three distinct but united persons: the Father, the Son (Jesus Christ), and the Holy Spirit. It is considered a central doctrine of Christianity and is based on passages in the Bible that refer to the three as separate entities, yet one in nature, will and purpose. The term "trinity" is not found in the Bible, but rather comes from the Latin trinitas, which means "three-ness". The concept of the Trinity has been debated and refined throughout the history of Christianity, and remains a topic of theological discussion and contemplation among Christians today.
