TRINITY. This means the union of three persons, the Father, the Son, and the Holy Spirit in one (unified) Godhead or divinity, so that all three persons are one in unity and eternal substance, but three separate and distinct persons as to individuality (1 John 5:7, 8; Dan. 7:9-14; Matt. 3:16, 17; 28:19; Acts 7:56-59).
The Bible never speaks of the Father dying, but it does say that the Son died (Rom. 5:10; Heb. 6:6; John 3:16-18). The Son died in the same sense that other men die--the inner man left the outer man (James 2:26). This proves that the Father and the Son were two separate persons.
