What is the Trinity? Many skeptics seem to misunderstand this important doctrine of Christianity as a pagan idea or a motorists idea, but a brief explanation of the Trinity will explain that neither of these are correct the core doctrine of the Trinity. It can be said in three sentences, there is one God. God is three Persons. Each person is fully God. This differs from a modeless understanding, which would say there is only one God who reveals himself in three different forms or persons. Whereas, the Trinity says there are three coexisting eternal persons who exist as one God. The Trinity also differs from a pagan grouping of gods who say there are three different gods who are simply one in purpose, but are fully separate. Whereas, the persons of the Trinity are not different gods but one God. Most of those who misunderstand the Trinity tend to classify the Trinity as one of these, but they are both incorrect the Trinity is not one God revealing himself as different forms. The Trinity is not three different gods the Trinity is one.
God is three persons and each person is fully. God the Father is first person of the Trinity. He is the source of the Godhead and all things. He has transcendent uncaused beyond mere existence. He simply is. The second person of the Trinity is the son, who is the word of the Father. He is eternally begotten of the Father and uncreated. His sources are in the father and humans can approach the father through the son. The third person of the Trinity is the Holy Spirit who is neither begotten nor created he. He eternally proceeds from the father. He is the active agent of God in the world and the guide of the church. His sources are in the father as well, yet he has always existed. It is important to mention that the members interact with one another.
In the world, the father sent the Holy Spirit like a dove onto the son at his baptism. The son sent the Holy Spirit at Pentecost. The Father created the world through the Son and the Holy Spirit. There is present interaction within the Trinity now, while the father is the ultimate source. The Son and the Holy Spirit are not less in power or divinity, they are all eternal and all fully divine. They all coexist as one God, yet are separate persons of one undivided essence. They are eternally loving in love one another in perfect harmony so there is no disagreement or division within the Trinity. They all share the same nature of God.
A not so perfect analogy has been likened to the Sun. There is the star, the heat in the Rays as long as the star has existed it has been generating rays and heat has proceeded from it. Likewise, as long as the father has existed, he has been pouring out his being into the Sun and the spirit has been proceeding from him. It is important to understand what the Trinity is, there are three persons of one God who co-exist eternally as one God. Each is fully God and fully divine. The Holy Spirit and the Son submit to the Father's authority because there cannot be two masters. They find their source in him, yet have always existed so again there is one God. God is three persons; each person is fully God. Now of course, there are many questions that stem from the Doctrine of the Holy Trinity, but makes the most logical sense of what is taught in Scripture.
