Muslims believe Jesus (ʿĪsā in Islam) was a prophet, not divine. They often point to Nicaea as the moment when his original monotheistic message was altered to elevate him to “Son of God.” The Nicene Creed affirmed Jesus as “true God from true God,” which Muslims see as a departure from pure monotheism (Tawhid). They argue this was a human invention, not divine revelation. They also claim that the concept of the Trinity was made-up at the council and was not present in the first century.

The Qur’an (revealed later in the 7th century) explicitly rejects the idea of Jesus being divine, presenting itself as a correction to what Muslims view as distortions introduced at councils like Nicaea. Muslims also highlight Nicaea as the moment Christianity diverged from the prophetic tradition of strict monotheism, which Islam claims to restore.
