Chrish, how much do you value this friendship? One of the current problems in this world today, at least in the USA, is that people are way too busy minding other people’s business, to the point of getting government involved in our private lives. I realize that you’re not suggesting getting the government involved in your friend’s private bedroom life, BUT is it truly your concern? And will such a discussion end or diminish your friendship?
I’m assuming that you care greatly for your friend and want her and her husband to be free of that sin, and that it’s because of your Christian love for her that you are considering this conversation. They will be held accountable for adhering to their beliefs, according to the way we’re now taught, and should they ever convert to Catholicism, they’ll essentially have a “get home free” card, since sterilization isn’t against the faith tenets of their current religion.
Unless the three of you sit around talking about sex, or how THEIR sex life is pleasing or not pleasing to God, I think you’re venturing into “No Man’s Land!” I don’t believe that ANYONE, other than a spiritual advisor, or medical representative, should broach bedroom topics with someone else unless that someone else has first introduced the subject.
If you and your friend discuss the upcoming vasectomy and you mention that no devout Catholic could ever consider vasectomy because…or that you could never condone your husband doing such a thing because…and she is receptive or asks questions, that is one thing, but if YOU initiate the subject with her and tell HER why it is wrong for THEM according to YOUR Catholic faith, that is quite another thing.
It’s difficult to put yourself in her shoes because the Protestant faiths don’t require their followers to adhere to all the rules that we must follow. If your friend and her husband believed that you must let rattlesnakes crawl all over you in hopes of not getting bitten in order to prove that you are a true believer in Christ, and were adamant that unless you subjected yourself to the possibility of the snake bites, you had no chance of going to heaven, would you be offended? Would you think they were nuttier than fruitcakes, but still love them, anyway? Would you still count them as your friends? Would you steer clear of them in the future?
I’m guessing that since you asked the opinion of others, you actually do have some reticence about following through with warning them. Think about this thoroughly and know all the fine points so that you can make a good case against sterilization, if you decide to go ahead with it. I can see such a discussion going okay, but ignored, with some of my friends, and simply ending friendships with others. You know your heart and conscience and those of your friend, so let them be your guide. Best wishes to you in whatever you decide to do.
