Everyone, clearly, would like to minimize or elimanate abortions. Santorum has gone so far as to state that he'd be in favor of states' rights to prohibit contraception, a move that certainly would increase abortions. I've heard many argue that life begins at conception. If that's the case, what is the harm in keeping the sperm from reaching the egg? However, if the belief is that the heavenly frequencies contain unborn souls waiting for an earthly vessel to inhabit, banning contraception would make sense. My question is whether the Catholic faith endorses the idea of pre-born souls. Is this the basis for the desire to ban contraception? What drives the Catholic battle against contraception?
