A theoretical situation came to my mind and I wanted to ask about it here. What if I, a devoted Reformed Christian in a Christian college, came across a girl. We like each other, I think about asking her out, but learn she is a Roman Catholic. Or even worse: we date for awhile because she says she is Christian, but later learn she is Roman Catholic. Should I say no (or in the latter case, break up)? My initial thoughts are yes, I should. I would not want the relationship to go further and to eventually marry and have children when she is a member of an organization with a false gospel (whether or not she herself is saved). This would cause major problems with conscience if one of us were not to eventually compromise on a very central point of the Gospel. I likewise was grieved when someone told me their dad is a Presbyterian and their mother is a Roman Catholic. Should that ever happen? Maybe I’m thinking on this wrong... Thoughts?
