In some countries a religion is not considered holy unless you have a few animals slaughtered on an alter to give it the real 'holy' feeling to the ceremonies.
I agree with sademo the reason for being in any religion is if you agree with them doctrinely their teachings. Just joining for social reasons or because the of the 'holy feel' to it's ceremonies, or it has a charassmatic leader like TV evangelists is for me being letting yourself fooled by the glitter and glitz of a religion.
I can enjoy the beautiful singing of a choir in a church ceremony but it just shows their skill and a good tune not holiness.
When a magician does a magic trick he creates a vivid atmosphere with loads of glittery wrapping that involves you deeply into the experience so your ready to take in what he does.
ceremony is just wrapping, a man praying alone in a bare desert can be extremely holy by who he is praying to and by his heart than all the pomp and ceremony put in for those involved.
that why for me it's all about the massage and we should believe what we join whether you are RC, mormon, scientologists or Jehovah's witness etc.
