Who constructed the doctrine of the Trinity? When was it constructed? Why was it constructed? What is contained in the Trinity? How can God have three beings and yet be one God? These are a few of the questions which are asked about the Trinity.
The authors of the Trinity are called the Cappadocian Fathers. Among these men and most important are Gregory of Nyssa, Gregory Mazianzen, Basil, Athanasius, and Augustine. Why was the Trinity composed? It was composed because of the rise of great heresy in the Church. One of these heresies which is well established today is Arianism, which believes: 1) Christ is God, yet he was created and had a beginning. 2) Acknowledged he is one with the father, but is united to Him like the rest of the faithful, although in a special manner. These fathers used many terms not found in the Bible. They used these terms in order to set forth as accurately as possible what had been revealed. One of the amazing things is that during the Reformation when everything was ad fontes the Trinity stayed.
The Trinity consists of three persons united into one, whose sole council is one. As one, the three persons will one thing but as the three persons fulfill their own part as the Father, Son, and Holy Spirit. Each of the three persons in the Trinity are very essential. We must keep all three, or else we have nothing.
God the Father is the ruler of all. He is the cause, origin, and beginning of all things. He is the one who created heaven and earth out of nothing — Ps. 33:6. To him we turn and lean on and set our life unto. For as we know he is our Creator. It is no wonder we cannot help but look up to his greatness and wonderfulness for without his will we would still be dust, for God does not need us to live — we need him!
Christ the Son is the word, wisdom, and image of the father. He is a Godly person who is our Savior and Redeemer by his blood. He was neither made nor created, for if he was lie would become a creature. He is from eternity as is said by the prophet Micah: “His goings forth have been from of old, from everlasting.” By the apostle, “He hath neither beginning of days nor end of life.” Christ is called God, the Word, the Son and Jesus Christ. Moses said “God created the world.” John said, “All things were made by that Word, which is called God.” — John 1:1-5. He is the only way to salvation and deliverance of sin. The Son is also our chief prophet and teacher because he hath revealed to us the secret counsel and will of God for our redemption. He is our only high priest because he has made one sacrifice for all the elect and that sacrifice was his holy body and also because he made continual intercession with the Father for us. He is also our eternal king because he governs us by His Word and Spirit.
The Holy Spirit is the eternal power and might and proceeds from the Father and the Son and is neither made nor created. He is given to a Christian so the Christian may have true faith, be comforted. He abides with the Christian forever. He is our sanctifier by his dwelling in our hearts. Also makes it possible for a Christian to partake of Christ and His benefits.
The unity of the three persons of the God head is found in the Old Testament, Gen. 1:26 and 27, Gen. 3:22, and the words “God created.” All deal with creation of earth and man. The New Testament shows the three persons of the Godhead clearly. In Jesus miracles He said, “Thy sins are forgiven thee.” For we know only God can forgive sins. The baptism of Jesus, 1) the voice out of heaven, Father; 2) Jesus in the water. Son; 3) The dove descending from Heaven, Holy Spirit. Also in the Old Testament in Deut. 6:4 states that God is one and against no one.
The Christian ground on believing the doctrine of the Trinity is the clear teaching of the Word of God. It is the operation of the Persons in the Godhead of which the Christian becomes aware through spiritual experience.
Is there anyone who can understand the Trinity perfectly and completely? I don’t think there is, for the Cappadocian Fathers could not even define in the terms they used. There is still reassurance for we do not need to understand each definition and term perfectly to have salvation or to receive the gifts of salvation from this understanding.
“I cannot think of the one, but I am immediately surrounded with the splendor of the three; nor can I clearly discover the three, but 1 am suddenly carried back to the one” (Gregory Nazianzen).
