What Happened at the Council of Nicaea? A Biblical Foundation for Understanding the Early Church's Greatest Theological Debate

This five-chapter course traces the biblical foundations for understanding the Council of Nicaea (325 AD) by anchoring each lesson in Scripture passages that were central to the debates. Rather than beginning with history, we start with what the biblical text itself reveals about Christ's nature and His relationship to God the Father, then show how the early church wrestled with these very passages during the Nicene controversy. Each chapter builds progressively, moving from the clearest biblical statements about Christ's deity, through the specific theological crisis that prompted the council, to understanding how Constantine's involvement shaped the outcome, and finally to the lasting significance of Nicaea for our understanding of the Trinity today.

The Word Was God: John 1:1-18 as the Textual Foundation of Nicene Theology

John 1:1-18 (ESV): In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that has been made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it...And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.

Christ as the Image and Sustainer: Colossians 1:15-20 and the Question of Christ's Pre-Existence and Deity

Colossians 1:15-20 (ESV): He is the image of the invisible God, the firstborn of all creation. For by him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things were created through him and for him. And he is before all things, and in him all things hold together. And he is the head of the body, the church. He is the beginning, the firstborn from the dead, that in everything he might be preeminent. For in him all the fullness of God was pleased to dwell, and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross.

Arianism's Challenge: Understanding the False Teaching That Prompted the Council

Philippians 2:5-11 (ESV): Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.

The Exact Representation of God's Being: Hebrews 1:1-14 and the Nicene Definition of Christ's Substance

Hebrews 1:1-14 (ESV): Long ago, at many times and in many ways, God spoke to our fathers by the prophets, but in these last days he has spoken to us by his Son, whom he appointed the heir of all things, through whom also he created the world. He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high, being made as much superior to angels as the name he has inherited is more excellent than theirs...But of the Son he says, 'Your throne, O God, is forever and ever, the scepter of uprightness is the scepter of your kingdom.'

One God in Three Persons: How the Council of Nicaea Affirmed What Scripture Teaches About the Trinity

Matthew 28:19 (ESV): Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit; 1 John 1:1-3 (ESV): That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon and have touched with our hands, concerning the word of life—the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us—that which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ; 2 Corinthians 13:14 (ESV): The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all.
