Myth, History, and the Council That Shaped Christianity For over 1,700 years, the Council of Nicaea (AD 325) has been burdened with claims that refuse to die. That Emperor Constantine invented the Trinity. That the divinity of Jesus was decided by political vote. That the Bible was assembled to suit imperial power. That Christianity reshaped itself by absorbing pagan ideas. This book subjects those claims to serious historical scrutiny. Drawing on early Christian sources, conciliar records, and modern scholarship, Luke J. Wilson guides readers into the real world of fourth-century Christianity. He explores why Nicaea was called, what theological questions were genuinely at stake, how the bishops understood Scripture and doctrine long before the council met, and what the creed was actually intended to protect. Nicaea emerges here not as a moment of invention or corruption, but as a moment of clarification-rooted in beliefs already preached, worshipped, and defended under persecution. The result is a clearer picture of how early Christians understood Jesus, the Father, and the Spirit, and why those convictions mattered enough to fight for. Written for both sceptics and believers, What Really Happened at Nicaea? is an accessible, carefully researched guide for anyone who wants to move beyond internet myths and encounter the council on its own historical terms.
