I don't remember what religion that is however by asking this question you are sinning.
With all this being said, I would guess that you are not in the right religion for you.
You see there are many good religions out there including the one you are in.
However some of the rules make some of these religions hard to live by.
For instance pretend your wife would die without a blood transfusion. However your religion does not believe in it. So you sit there and watch her die. This to me would be hard to do, however for this religion it is something they go through and accept.
The question you need to ask yourself is am I truelly this religion or do I need to find a different religion where you can ask questions.
Being as religious as I am I know there are times when you need to make tough decisions like the one I'm giving you.
The example I gave you was a on trial and somebody asked me my opinion. A woman was and is still in a coma. Her parents say she's Christian. Husband says she's his religion (which doesn't believe in blood tranfussions). Her life is on the line.
My view, sad and cruel as it may seem is to not grant her a blood transfussion. By not giving her one you are not going against her Christian beliefs (if she was Christian), however by giving her one you would be going against her other religion beliefs (if she was that religion).
The courts ruled to give her one. So I hope she is Christian. If she wasn't it would cause damage to her and between her and her family.
I hope this helps.
I only put the Christian religion name in here so that the other religion doesn't get bad mouthed. I don't see anything I said to be able to give reason to bad mouth Christians.
