Im a protestant - should i date a catholic girl?

One obvious agreement you should have before marrying is the church your children will go to. It is preferable that you settle this issue well in advance. The catholic believes in eenism, that is being open to all religion, there is no need for anyone to change religion, the religious practice of each of the couple can continue, although it is preferable if they can have unity in the practice of faith as this will benefit the children.
