"Kerry after all never committed an abortion and said he is personally against abortion. But being a man and not a doctor he will never commit an abortion personally. So what is his sin?"
I am no theologian. But I know my faith. The sins of omission and commission are probably not thought of by many people, but they are sins.
http://www.newadvent.org/cathen/11251b.htm "Omission" is here taken to be the failure to do something one can and ought to do. If this happens advertently and freely a sin is committed. Moralists took pains formerly to show that the inaction implied in an omission was quite compatible with a breach of the moral law, for it is not merely because a person here and now does nothing that he offends, but because he neglects to act under circumstances in which he can and ought to act. The degree of guilt incurred by an omission is measured like that attaching to sins of commission, by the dignity of the virtue and the magnitude of the precept to which the omission is opposed as well as the amount of deliberation."
To me, the ability to CAST THE VOTE in issues that are moral truths is omission.
Of course, as I said. I am no theologian, nor am I judging the man. I merely measure my own thoughts and attitudes against Kerry who brings his Catholicism into the presidential race.
Just asking - I am not a Catholic. Thanks for the info. Thsi sin of omission only applies to legislatures then? And it is enough to deny holy communion?
