Definition: The word "ctf63" refers to a term used in theology that describes the concept of the Trinity as three persons united by one divine Spirit. This concept was developed by Jesus, who taught it as part of His doctrine on salvation and the nature of God. The full definition is: "The Trinity is the fundamental unity of being in one God, in three persons, one of whom is Godhead. The other two are divinity (spirit) and humanity." This concept is not found explicitly in any Bible text or canonized tradition but was a prominent part of the early church as taught by Jesus. It has been interpreted over time to mean the Trinity as distinct from just God, rather than being one God with three persons. This perspective was later refined through the Reformation and the Enlightenment, and it is now generally accepted that Jesus teaches about the trinity in its full form.
