Though the Bible taught truth of the Triunity of God implicitly in both Old and New Testaments, the development and delineation of this doctrine was brought about by the rise of heretical groups or teachers who either denied the deity of Christ or that of the Holy Spirit. This caused the early church to formally crystallize the doctrine of the Triunity. Actually, Tertullian in 215 A.D. was the first one to state this doctrine using the term, Trinity. 9 Concerning the struggle the early church went through, Walter Martin writes:
As the New Testament was completed toward the close of the first century, the infant church was struggling for its life against old foes—persecution and doctrinal error. On the one hand were the Roman empire, orthodox Judaism, and hostile pagan religions, and on the other hand were heresies and divisive doctrines. Early Christianity was indeed a perilous experiment.
Probably no doctrine was the subject of more controversy in the early church than that of the Trinity. Certainly the teaching of “one God in three Person” was accepted in the early church, but only as this teaching was challenged did a systematic doctrine of the Trinity emerge.
The Gnostic heresy, for instance, (which permeated Christendom in the lifetime of the apostles) drew strong condemnation in Paul’s Epistles to the Colossians and John’s First Epistle. Denying the deity of Christ, the Gnostics taught that he was inferior in nature to the Father, a type of super-angel of impersonal emanation from God.
Following the Gnostics came such speculative theologians as Origen, Lucian of Antioch, Paul of Samosota, Sabellius, and Arius of Alexandria. All of these propagated unbiblical views of the Trinity and of the divinity of our Lord.
But perhaps the most crucial test of Christian doctrine in the early church was the “Arian heresy.” It was this heresy which stimulated the crystallization of thought regarding both the Trinity and the deity of Christ …
Today there are still remnants of the Gnostic heresy (Christian Science), the Arian heresy (Jehovah’s Witnesses), and the Socinian heresy (Unitarianism) circulating in Christendom. All of these errors have one thing in common—they give Christ every title except the one which entitles Him to all the rest—the title of God and Savior.
But the Christian doctrine of the Trinity did not “begin” at the Council of Nicea, nor was it derived from “pagan influences.” While Egyptian, Chaldean, Hindu, and other pagan religions do incorporate so-called “trinities,” these have no resemblance to the Christian doctrine, which is unique and free from any heathen cultural vagaries … 10"
