I agree with much of what has been said to the effect of marriage being vocational in nature. Priests have the Church in a way that the lay person will never have in this life. I personally believe that the Catholic experience is (or should be) the pinnacle or highlight of daily life. A Catholic should attend Mass almost everyday (when possible) because it is truly heaven on earth. Much of one’s day should be occupied with prayer and one’s commitment to Christ and his One, Holy, Apostolic, Church on earth should be strong and growing. (Sadly many Catholics are Catholic in name only.)
With that in mind, how could a devout Catholic enter into a non-Catholic vocation? (Marriage.) It would be like a Catholic Priest who fulfills all of his duties, but who enjoys a protestant bible study one night a week.
I think the problem is (and another poster pointed it out) that our society (and sadly many Catholics) see marriage as self fulfilling rather than “other”-fulfilling. I’m sorry, marriage is not merely for personal happiness. (As a married person I can tell you every moment is not pure bliss.) Marriage is a job, a vocation, a calling. If you are not called to it, you should not marry.
Another problem is that many people are Catholic, but don’t actually practice Catholicism. As a result they’ve bought into society’s version of marriage. This is even to the point where some Catholics will disagree with Church teaching on marriage. Archbishop Fulton Sheen once said, “When someone begins a statement with ‘I’m Catholic, but…,’ that person isn’t really Catholic.” Now, I understand that anyone who has had the sacrament of confirmation is technically a Catholic, but you know what he meant.
Conversely, if a person were a devout protestant, hindu, muslim, jew, or anything else, they would not want to marry a Catholic. Only those who are lukewarm in their beliefs want to marry out of their faith. Now, I’ll admit there are probably those who hope to convert their partner, and that is commendable, but not wise.
I know there are exceptions to all this. I’m sure there are some very happy devout Catholics who are married outside of Catholicism, but…no I take it back, how could you be truly happy if your partner was outside the Church?!?
Sorry for the disorganization of this post. Was hurrying to say a lot.
