Cynic and others raise valid points that we catholics must remember.
It can be tempting to declare that couples contracepting aren’t being at all loving and get NONE of the unitive benefit of marital sex. But morality is far more subtle than such over-simplifications. The contracepting couple surely DOES get some, perhaps most of the benefits of the unitive aspect of sex. But that good doesn’t negate the BAD effects that also sneak in along the way like a Trojan horse (yes, pun intended).
I promise to be careful not to convey the impression that catholic teaching on this matter is that couples who contracept obliterate all the beneficial aspects of God’s design for sex. Not the case. The fact that they introduce sin into the act no more obliterates all the good that is in it than does an entire marriage become worthless when a men tells his wife a lie about how many beers he drank when out with the boys. It’s a sin. It has REAL negative effects. But those who DO practice it don’t automatically lose all the unitive benefits of sex. But like that husband’s lie, and like the bulemics stomach acid eating into his/her throat, the sin has steadily building consequences over time and repetition.
As for those who argue that the early Fathers faulty scientific understanding negates their moral teaching about contraception, BEWARE! The fact that they did not have a proper scientific understanding of the nature of conception, does NOT negate the legitimacy of their moral teachings. If you believe that, then you probably don’t believe in the Eucharist anymore since the scientific idea of all matter having both “substance” and “accidents” is archaic and superceded by advances in science.
In both cases, the religious truth is still entirely true even though the scientific basis for the way it was originally explained has been replaced.
Upon further research, I think it might be better to revise my analogy of contraceptives to those ancient Romans who deliberately used vomiting as a means to prolong enormous feasts rather than bulemia. The former is ENTIRELY about self-gratification, while the latter involves complicated body-image issues that have no correlation in contraception.
For any catholics here who are taking the pro-contraception position, I have a question? Have you tried NFP for avoidance of pregnancy (assuming there is a serious reason)? Why not? What’s to be afraid of? Even if you don’t undestand the reasoning, don’t the hand-picked successors of the Jesus apostles deserve the benefit of the doubt for at LEAST a trial period? Would a year of living with NFP really kill you? Is the consistent judgement of the church for 2,000 years really something that ought to be ignored without serious investigation/trial?
Non-catholics, ignore the above questions. Of course, I expect you to not feel that the church’s advice should be taken. Why would you if you believe that everything that comes from the Catholic church is just the ideas of mere men?
