Why do some single Orthodox date those who are Heterodox? Being an inquirer into Orthodoxy coming from conservative Protestantism, I don't understand this. Scripture states in 2 Corinthians 6:14 "Be ye not unequally yoked together with unbelievers; for what fellowship hath righteousness with unrighteousness?" When I was Protestant I would have NEVER even considered dating someone who didn't share the same faith as I did; that is THE most important thing to have in common when dating (in a relationship which may eventually lead to marriage), in my mind. Less "fundamentalist" Protestants, however, wouldn't share this view and would have no problem dating someone of a different faith tradition. They might even consider such dating as "missionary dating" in the hopes that their boyfriend/girlfriend would be influenced by their faith and want to "convert" or switch denominations.
One of the single adults at the church I attend (who is Orthodox) is dating a person who is Protestant and on occasion has brought them to liturgy (and I'm glad that this visitor is being exposed to the Orthodox faith); this situation is what raised this question for me.
