Unfortunately none of this applies to the 21st C.<quoted text>
Never been done. Only the secular (non-Catholic authority) in Medieval times had any power to execute people. You see, you are falling for the same historical lies as the atheists, or propaganda issued by the early Protestants. Fox's Book of Martyrs, perhaps?
First, to truly grasp the situation, you must go to original sources. And when you do, as I have, you will find that:
Galileo was never treated unjustly.
The Crusades were not evil.
Medieval peoples did not believe the world was flat, or failed to bathe often, or were primitive in thought or deed.
That the Inquisition was evil (any of them), or had the power to execute people.(I learned this from a Jewish atheist who wrote about the history of New Mexico, and Crypto-Jews. Even HE had to tell the audience, before he could proceed with the lecture, that the Inquisition was not as we think.)
There are countless vile lies about Christian history. Naturally, because we are despised, as Jesus said we would be.
When I say the Church needs to get Medieval, what I mean is that it needs to ASSERT ITS FULL MORAL AUTHORITY OVER ALL ASPECTS OF LIFE. Governments included, since the separation of church and state never meant what most people think it means either.
That does NOT mean burning at the stake, which ITSELF was strictly anti-Christian, is being endorsed. Excommunication and exile are the only legitimate punishments, unless one continues to push their own beliefs as fact upon the population, then stronger measures MIGHT be justified.
And I am testing all of you. If the word "Medieval" conjures up ideas of witch burning, then you are ignorant of history. That is not at all what Medieval times was about. It was about the development of the most technologically advanced civilization the world has ever seen, about people that struggled to make a better world, who brought us science, and universities, and the Renaissance.
All of those that lie about Medieval people, and who they actual were, and what they actual did, are vile creatures.
You probably also applaud slavery, rape and incest, because all of these are in the Bible that you trust is "true".
You are deluded.
