Thanks for your comment! So how does one explain that to the one they love who has no understanding of Sacraments and grace?
Do you love your girlfriend/fiancee? Then your first priority needs to be the salvation of her soul.
The Church allows mixed-marriages between a Catholic and a Protestant or a Catholic and a non-Christian
if and only if it (through the bishop) thinks that it will lead to the conversion of the non-Catholic party. So if she is under the thumb of her family and does not know about the Faith and marrying her will free her from their control and allow her to be able to be free to learn about the Faith and be baptized,
then it is a good idea to marry.
Remember, there is a two-fold issue here. The first is that it is
impossible for a Christian (baptized person) to marry a non-Christian (non-baptized person). You may stand in front of a minister or a judge or even a Catholic priest and say your vows but if you do not have a dispensation, nothing happens – you are not married. The second is that it is very dangerous to marry a non-Catholic (or even a lapsed/weak Catholic), you have to be very strong and determined to pray earnestly and make sacrifices in order to convert your spouse.
Remember what St. Paul says:
2Cor 6:14-18 said:
Bear not the yoke with unbelievers. For what participation hath justice with injustice? Or what fellowship hath light with darkness? And what concord hath Christ with Belial? Or what part hath the faithful with the unbeliever?
And what agreement hath the temple of God with idols? For you are the temple of the living God; as God saith: I will dwell in them, and walk among them; and I will be their God, and they shall be my people. Wherefore, Go out from among them, and be ye separate, saith the Lord, and touch not the unclean thing: and I will receive you; and I will be a Father to you; and you shall be my sons and daughters, saith the Lord Almighty.
So your first priority must be to save her soul, far beyond that of marrying her.
If you think you need to marry her for her to be free to convert, talk to a good priest about it. If he agrees and believes that it is not a danger for you, he will put you in contact with the bishop. Then the bishop can give you a dispensation (an exception to the rules) in order to marry her. But if she is living on her own, concern yourself first with her conversion (a true conversion, not just getting a box checked off like some people who go through RCIA just to get married) and
then worry about marrying her.
I love my girlfriend and I want to marry her but she is a recent convert (Easter Vigil earlier this year) from a liberal/unorthodox Episcopalianism (blended with all sorts of New Age practices from tarot to astrology to Hare Krishnas). Until she settles down and begins a true devotion to Christ, I can’t marry her. Yes, legally I can but not morally. Her conversion comes first and she needs independence in order to facilitate that. And I have to look out for my own soul first (that’s not selfish, that’s reality), I don’t want to be drawn into false practices or away from the true religion, nor do I want her to go run off with some guru at some point down the road. I’ve been friends (not dating) with her for five years and it may be another five before I can marry her but it will be worth it.
If your girlfriend is worth marrying, she is worth waiting for.
