As an evangelical Presbyterian, although I would have preferred to hear a case built on the bible first, rather than simply logic, however, I cannot find fault in Dr. Miris's clear and cogent reasoning. The more I see the fruits of easy sex (I hate to call it the "sexual revolution")--which historically directly follows the availability of contraception, with the culture of death from abortion also quickly following, the more I'm considering that the Roman position on contraception may well indeed be the most godly one.
Still I would think the issue for American Roman Catholic curia would be to find a way to make their case more compelling to average American Roman Catholics (like Sean Hannity) who, I believe, seem to approve of and use contraception as much as those of other faiths. That disconnect, of official Roman teaching, verses, typical lay practice, is one serious issue that evangelicals like I have with Roman Catholicism.
There is no question that contraception has led to some bad things - fornication by those who would formerly have been deterred by the risks; the notion that using contraception is the same as having a right not to be pregnant, hence abortion; birth rates that are too low in some parts of the world; the idea of procreation as an optional part of marriage, etc.
You could also name good things - women not worn down by childbearing and childrearing, families not having more children than they can provide for, women being able to enter other spheres than motherhood - couples being able to have this and the closeness, pleasure, release of intercourse.
Guns facilitate plenty of bad things. Horrible, immoral, unChristian things. Not many people here would say, ban guns.
You are right that there is a vast disconnect between the teaching of the Church and the ordinary Catholic. I am not sure how it can be bridged.
