There's a lot i don't believe in when it comes to christianity. My pull to just follow the bible and this whole fellowship with god and following his way, and being practical and realistic.
What's in the bible is what's in the bible. Now the only case where this is prime for conflict is mormonism with the other book. I hate it when people try to take away from it, or add on to it. Neither should happen. But, denominations are a great way to add to and take away from the bible in a strong, literal, or subtle way. Each denomination believes in certain ways, different things, or doesn't believe some stuff.
Confession to a priest is sort of a dumb. You don't need to confess to a priest when you can confess to god directly. But hey, some people like the tradition (good for them), just as long as they understand it's not the only way you can confess to god. But, many times it will be purported as the only way to confess your sins.
Speaking in tongues is retarded. I forget where it says in the bible, but it's something that fools do. One of the reasons i hate speaking in tongues is more of a personal reason other than the fact that it's dumb. My mom kept trying to get me to do it by making me feel guilty by saying "when you speak in tongues you're actually praying for the people that need prayer that you don't know that you're praying for that you need to pray for". God doesn't impose impossible burdens upon us like this (those that don't believe this can have fun with their zues complex). The other part of this that speaking in tongues is supposed to be like a gift from god to man. Speaking garbledeegook is not a gift, it's something that you can just do. FLAMAJAMA! I wouldn't even really call speaking in tongues a tradition or ritual..whatever. Speaking in tongues is comparable to a person who's too drunk to talk or do anything.
Baptism with what i know about it, which isn't much but is pretty brief. Baptism in assembly of god churches from what i know use it as a personal affirmation for when a person is ready to be fully submitted to god. My only reasoning for why it's dumb is for similar reasoning why confessing to a priest is dumb. You can tell god yourself if you're ready to be fully submitted, you don't need a physical act to do this. But hey, some people like the tradition (good for them), just as long as they understand it's not the only way to let god know you're fully submitted to him. But, many times it will be purported as the only way to show god you're fully submitted to him and ready to follow his direction.
The other thing i find highly retarded about christianity is the rejection of science. I don't like this because it means there's a rejection of learning how the universe around you works. Knowing how the universe around you works is sort of necessary to stay alive. Stuff like gravity and how the earth is on a tilt and that causes the 5 seasons. I think the rejection of science in christianity comes from pastors and priests who get the shepherd complex and that they must lead the sheep, so just like governments they will use misinformation and lack of information to lead the sheeple. Even going so far as saying science is evil. Saying science is evil is taking it too far for me. That's like saying god gave us a brain for us to not use, scientific theories lead you down the path of beastiality, and finding out the anatomy of the helium atom is next to the invention of the guillotine. Dumb people are easier to lead for whoever has an agenda.
And lastly, what's up with the hijacking of pagan holidays? Christianity appears to have an archaic need for hijacking of many things. Hmmmm, veterans day, we churches need to get together to figure out how make this just about god, not the veterans. Hijacking holidays and other things is just vain.
