Should You Believe in the Trinity?

THE Bible was completed in the first century C.E. Teachings that led to the development of the Trinity began to be officially formulated in 325 C.E.​—more than two centuries later—​at a council in the city of Nicaea in Asia Minor, now Iznik, Turkey. According to the New Catholic Encyclopedia, the creed attributed to the Council of Nicaea set out the first official definition of ‘Christian orthodoxy,’ including the definition of God and Christ. Why, though, was it deemed necessary to define God and Christ centuries after the Bible was completed? Is the Bible unclear on these important topics?

When Constantine became sole ruler of the Roman Empire, professed Christians were divided over the relationship between God and Christ. Was Jesus God? Or was he created by God? To settle the matter, Constantine summoned church leaders to Nicaea, not because he sought religious truth, but because he did not want religion to divide his empire.

Constantine asked the bishops, who may have numbered into the hundreds, to come to a unanimous accord, but his request was in vain. He then proposed that the council adopt the ambiguous notion that Jesus was “of one substance” (homoousios) with the Father. This unbiblical Greek philosophical term laid the foundation for the Trinity doctrine as later set forth in the church creeds. Indeed, by the end of the fourth century, the Trinity had essentially taken the form it has today, including the so-called third part of the godhead, the holy spirit.

Jesus said that “the true worshipers will worship the Father with . . . truth.” (John 4:23) That truth has been recorded in the Bible. (John 17:17) Does the Bible teach that the Father, the Son, and the holy spirit are three persons in one God?

For one thing, the Bible does not mention the word “Trinity.” For another, Jesus never claimed to be equal to God. Instead, Jesus worshipped God. (Luke 22:41-44) A third line of evidence concerns Jesus’ relationship with his followers. Even after he was raised from the dead to the spirit realm, Jesus called his followers “my brothers.” (Matthew 28:10) Were they brothers of Almighty God? Of course not! But through their faith in Christ​—God’s preeminent Son—​they too became sons of the one Father. (Galatians 3:26) Compare some additional scriptures with the following statement from the creed attributed to the Council of Nicaea.
