Of Religious Power, Castration, and the Nicene Creed A great read. My thoughts.
People want to be part of the majority. Depending on where you are, that's Christianity. Anyone can say they're anything and be accepted as that solely by the fact they said so. Not everyone lives by the main tenets of their own professed religion. This one being "Love God with all your heart, mind, and soul" and "Love others as you love yourself". A wonderful ideology. There would be much less suffering, strife, and war if this was adhered to by all.
Taking history at face value (did you witness it or any 'evidence' being discovered yourself? You can carve over a 5,000 year old artifact and guess what. It will carbon date the same.) I read Constantine (or others near him) witnessed miracles first hand one of which being Christians thrown into boiling oil yet being unharmed. Let's face it that's pretty cool and more than enough to make you think.
As far as the 'domination of thought and conduct' aspect that's one of the main criticisms of all religion. It's a control mechanism. It definitely is used as such by some however if the premise is true, there is a God and we are to live peacefully 'or else', well that would be that wouldn't it? Look at some factions of society, here and everywhere. The violence, animosity, and suffering. An atheist would note the positive benefits religion has for not just others but even them.
From my understanding Christianity is essentially the belief that the prophecized Messiah or 'redeemer' who allows us to make mistakes and sin or essentially 'just be human' without eternal damnation was in fact, Jesus Christ. Older religions do not believe this and that the Old Testament laws still apply. Some do believe in a Messiah/redeemer who will arrive and do this, simply that it was not Jesus.
All that aside I'm skeptic minded myself. I wouldn't say it's impossible the religious books we have today are not the original texts. Or that things weren't added or omitted.
