By 610 A.D., Christianity had already been transformed into an imperial religion.
Beginning with Constantine, political power had been used to establish and defend Trinitarian Christianity. The councils defined Jesus as divine, the Trinity became the foundational doctrine of Catholic Christianity, and the Church increasingly claimed universal authority over religious truth.
This was the world in which Muhammad appeared.
Around 610 A.D., he began proclaiming revelations that would later form the Qur’an. His central message directly challenged the foundation of imperial Christianity: God is one, and Jesus is not God but a messenger.
Islam therefore arose as a reaction to the Trinitarian religious imperialism that had developed since Constantine. Muhammad claimed that the worship of the one God had been corrupted and that his message restored the faith of Abraham, Moses, and Jesus.
In my interpretation, Muhammad is the great star of the Third Trumpet.
The star falls from heaven because Muhammad entered history claiming to bring a revelation from God. It burns like a torch because his message appeared as a new light confronting the religious system that dominated the Christian world.
The star falls upon the rivers and springs of water.
These rivers and springs represent the sources from which people receive their understanding of God and revelation. The Qur’an entered those sources by presenting a new account of Abraham, Moses, Jesus, prophecy, law, and judgment.
Islam rejected the Trinity and the divine identity attributed to Jesus, but it did not simply restore the original Revelation. The religious traditions inherited by Muhammad had already been shaped by centuries of Jewish and Christian interpretation. The Qur’an reorganized those traditions around Muhammad’s prophetic authority and became a new source of faith for entire peoples.
The waters became bitter because the appearance of Islam created a second universal religion claiming authority over the same prophetic history.
Christianity proclaimed a Trinitarian God and a divine Christ. Islam proclaimed one God and a human Jesus who was a messenger. Both claimed Abraham, Moses, and revelation. Both claimed to represent the truth for humanity.
After Muhammad’s death, Islam rapidly became a major religious and political power. Large territories formerly controlled by Christian empires came under Muslim rule. The religious monopoly of imperial Christianity was broken.
Christianity and Islam then developed as two rival universal religions. Their later history was marked by territorial expansion, political competition, theological conflict, and repeated struggles for authority.
The Third Trumpet therefore marks the appearance of Muhammad and the rise of Islam within a world already dominated by Trinitarian imperial Christianity.
610 A.D. is the moment when the star fell, a new claim to revelation entered the rivers and springs, and the religious history of the world was permanently changed.
