The Church warns against marriage to non-Catholics and non-believers for good reason. It requires permission for mixed marriage and a dispensation for disparity of cult (marriage to an unbaptized person).
I personally don’t recommend it because I don’t think it’s prudent. I think it can be dangerous to the Catholic’s faith, I think it can be dangerous to the children’s faith, and I think that it can cause strife in a marriage. That’s why the bible warns against it. I know there will be countless anecdotal stories about how it “works” in their marriage-- but I don’t think you should set out to marry a non-Catholic. I personally did not entertain that in any way, I did not date non-Catholics once I became a Catholic. Most of the time when it “works” one of the two parties is non-practicing or indifferent in their own faith and let’s the other raise children in the other faith, goes to church with the other, or remains silent/doesn’t interfere with the other. Indifference is hardly a great example for the kids. And if both are devout in their own faiths-- that’s a recipe for disaster.
Obviously the Church allows it as a mercy to those who don’t heed its warnings, but it shouldn’t be treated as no big deal.
