Jerry Rassamni begins the book with the story of his conversion. Born in Liberia of Lebanese parents, he grew up in Lebanon as a secular Druze Muslim. He says that, as a youth, he never thought in religious terms, yet he became caught up in the Lebanese civil war and lived as a militant Muslim. Hatred and killing hardened him. Then it disgusted him. Looking for a way out, as soon as he had the chance, he came to the U.S. seeking an education. While in Texas, he met and married a Christian woman. Soon, he attended Bible classes, never expecting to join the church, but while there he learned to know and love his Savior.
The main part of his book is a detailed analysis of the weaknesses of Islam and the strengths of Christianity. Its goal is to create doubt in the minds of Muslims: doubt about the holiness of human nature, about the reliabiliity of the Qur'an and Mohammed, and doubt about the truthfulness of Islam's theology and traditions. At the same time, the book confesses the Christian faith in order to draw readers to trust the love of God in Christ Jesus, our Savior.
The Constantine Codex involves readers in an intriguing search for a rare Third Century copy of the New Testament. The search leads to Istanbul where discovery of the codex arouses the passions of zealous Muslims who try to destroy the precious document.
Of particular interest for many readers is a public Christian-Muslim debate that the book stages in Istanbul at the famous Hagia Sophia. It illustrates the challenge that Islam presents to Christianity and how the Christian faith more than meets that challenge.
The Constantine Codex is one of a series of popular novels written by noted historian Dr. Paul L. Maier dealing with archaeology, Christianity, and with opposition to the truth.

The introduction states: "Muslim theologians make no distinction between the Quran and the Hadiths. Both are considered works of revelation or inspiration.... In the Quran Allah speaks through Mohammad; in the Sunnah he acts though Mohammad....The Quran cannot be understood without the aid of the Hadith, for every Quranic verse has a context which only the Hadith provide."
