“This has somewhat weakened Christianity’s political power. “
Anyone wanting to gain political power could join Islam. Now that is a take-no-prisoner style powerful religion.
If you wanted a society based on Islamic theology, yes. It has actually been remarkable in terms of staying power and expansion.
Unfortunately, those who want the Christian ethic to be one that is dominant in society have a harder job than Muslims do. Islam after all, does not have a left wing trying to destroy it.
Things such as Islam are why Christians need Earthly power. I can’t decide if you think something along the lines of God will save you from them or you would not be in need of saving if Islam held all current Judea-Christian political power? At first I thought that was a trollish post but after reading some of your other postings I am very curious of what makes you tick.
