I understand if you can’t answer this, but I thought I would give it a shot. It’s obvious from your question that have a religion that you practice.
You didn’t share specifically what it is, so I can’t be as specific as might be needed.
We live in an age where is extremely easy to meet someone under normal, everyday circumstances who is attractive in many ways, but does not share your religious affiliation and beliefs. No matter what your religion, in today’s society, moral issues surrounding sex (i.e., chastity, premarital sex, contraception, etc) seem to have become a non-issue.
For most of us, we are exposed to all kinds of people. It seems that everything about society has a pro-sex message and purpose.
(Even though I don't think anyone is required to pray to a saint, and the doctrine is a little more complicated than that.) If he believes that non-Catholics aren't true Christians or that the Lord's Supper can only be practiced in the Roman Catholic church, then he would never be at home in your tradition.
If you're committed to whatever tradition you're a part of, and he's committed to Catholicism, pursuing a relationship seems like a bad idea.
It's considered the core definition of Christian orthodoxy.It does make a difference if you are a baptized Christian of one of the thousands of Christian denominations, or a non-baptized person of another religion.What makes no difference, however, is the fact that you belong to another faith, and that causes concerns for both parties.Catholics also see marriage between Catholics as an essential way of passing on the Catholic faith from one generation to the next.America is, however, a society in which Catholics and people of other religious faiths encounter each other each day.
