I think the whole problem here is people misunderstand the teaching due to the bluntness of answers on the subject.
If you simply tell me “Yeah if someone is impotent they CANNOT marry” it sounds blunt, intimidating, and a little offensive, and frankly as a newcomer to the Catholic faith, yes, I can see how it can easily scare someone away from the church when they don’t understand.
If you say something with a bit more sensitivity, or maybe explain a little bit with the realization that there are newcomers to this belief and how it works, by adding something like “It is just part of marriage that one partner has the right to have sexual relations with the other”, it is a lot easier to accept and understand. For me at least.
I love my girlfriend, and our love is the reason I want to marry her. We are going to be together because we love each other. And we started our relationship before I even started pursuing my faith in the Catholic Church, and I am by no means saying that I regret the Holy Spirit starting the fire inside of me to pursue my faith.
What I am saying is that I personally believe in marriage being between two people who truly love each other. That is what it will always be to me, no matter what anyone says (Maybe for some people they don’t need love. Good for them I guess, but that doesn’t work for me.) And yes, I believe sex is the embrace of love between husband and wife, and it should be able to be had. And procreation is important in further expanding the love between the two, while being able to share a new love with an entire family.
All this time, our faith in God can be shared and built initially between the husband and wife, and eventually shared with the kids as well. Our faith in, and love for God can also be increased by the understanding that he is the source of that love that we all have for each other.
I don’t support the liberal movements that are going on these days, and I don’t think that it’s right that everyone thinks that they can split from the church teaching/standings on things. But I don’t think that what I think on the subject is too much of a liberal way of believing. It complies with this church teaching, as I don’t believe people can be married without being able to have the marital embrace, but it adds that I believe love can be (and is for me) what brings two people together for marriage.
Our God is a relational God, is he not? I believe he smiles when he sees a man and a woman who truly love each other coming together in Holy Matrimony.
