Is it wrong to use Birth Control (contraceptives)?

I have not been closely following the ongoing argument on whether or not Catholic (and other religious) institutions have to provide medical insurance that guarantees free birth control, tubal ligation and morning-after abortifacients — all of which violate church doctrine on the sanctity of life.

To me, I feel that since a high percentage of Catholic women already use some form of birth control, the least that the Church (or other religious insitutions) can do is provide that for free to the women who work for them.

I would like to hear all aspects and point of views of this (women, men, religious, non-religous, etc). I also can’t say that I’ve read the bible, so if anyone can point out the specifics of why using contraceptions is considered a sin and violates the sanctity of life.

Maybe there are other passages in the bible that contradict the passages that frown upon contraceptives, again I do not know what all is said in the Bible. I hope this doesn’t get “TOO” political, but I suspect it won’t be too long before the politics get involved.
