This came up in discussion not long ago.
Premise 1: If I believed Islam was a religion from God, I would be Muslim.
Premise 2: I’m not Muslim.
Conclusion: Therefore, I don’t believe Islam is a religion from God.
Islam and Christianity cannot both be right. Any Christian who says Islam is a message is mistaken about Islam or Christianity. The two religions teach opposite different things about:
- the Crucifixion and Resurrection
- And so on.
The teachings cannot be reconciled. To try, you must distort the teachings of both.
As to how and why? Maybe I’ll elaborate on these another time.
