Most of the critics of Christianity really have no measure of the full meaning of religion.
“Christianity has not been tried and found wanting, it has been found difficult and left untried.” - G.K. Chesterton
There are religions founded on the hard-won lessons of what is moral and just, and there have been religions which have discounted these lessons, only to become, at best, a footnote on history, and largely discarded, because of their implicit cruelty and adoption of tyrannical methods.
But because some sort of ideology may declare itself to be a “religion”, does not mean that morality and justice are somehow discarded, simply because despotism is now held to the the guiding virtue. Despotism has a way of finally exasperating those subject to its whims and error to finally rise up and give it a smack.
For a period of a thousand years or more, something that called itself “Christianity” fell into the category of support of despotic ideologies, and while it claimed control of a fairly wide expanse of the planet, it finally came to its confrontation with internal schisms and compounded error, and underwent a vast reformation. The Christianity of the 18th and 19th Centuries was entirely different from the earlier institution that existed during what we know today as the “Middle Ages” or the “Dark Ages”.
What we have today is an existential threat to that enlightenment, and a distinct possibility of sliding back into that “Dark Age”, when despotism in the name of religion would again be imposed upon the world.
