From a reader…
I am 20 years old, and I believe that contraception is immoral. My parents do not. This has caused much strife at home. We went to our trusted parish priest together to discuss it. He told me that certain circumstances within marriage can make contraception justifiable. Now my parents believe the matter settled and think I am all the more unreasonable for not changing my mind. What should I do?
Your “trusted parish priest” is wrong.
Review Humanae vitae, Evangelium vitae, Donum vitae, and Dignitas personae for the definitive teaching.
There are narrow circumstances in which one spouse can without sinning endure its use when it is pretty much inflicted by the other spouse, but that does not justify its use. Furthermore, invincible ignorance can mitigate the sinfulness of its use, but it does not justify its use.
If the issue is causing a lot of strife at home, it might be best not to discuss it. If your parents, having had guidance (bad guidance) from their parish priest about the advisability of birth control, are using it themselves, there’s nothing that you, their child, can do about it other than to pray that they receive more enlightened and better counsel.
You’ve discussed it, you’ve made your thoughts on the matter known, you’ve argued well (one hopes), and now might be the time to step back. Fraternal correction doesn’t flow “upward”, as it were from children to parents in matters such as these.
Entrust them to the Holy Spirit.
Furthermore, Christ’s teaching about the indissolubility of marriage cannot be changed.
(I just thought I’d toss that in there, because I can.)
Moderation queue is, of course, ON for this.
