When a couple do not share the same faith and same religious commitment, then when the going gets tough, where do they go for help?
The Orthodox Church allows marriages between Orthodox Christians and other Christians (not non-Christians).
In the best cases, the people involved had veto power; that is, neither one had to accept the match. We vainly imagine this power of choice is the same as freedom, but if we have no basis on which to choose other than our subjective urges, transient likes and dislikes, and fantasies based on movies, novels and occasional glimpses at internet pornography, then choice is not freedom but bondage: bondage to the ideals of a sick culture and the passions of a fallen mind.
Unfortunately, our culture has taught us that sexual attraction is key to finding a suitable life partner; in fact for much of our culture, good sex is the highest form of transcendence conceivable.
Single Orthodox Christians have no easy road before them, especially if they suspect that they will be married some day.
For most of history and in a large but shrinking portion of the Orthodox world today, single people did not have to worry about who they would marry: someone else chose for them. We cannot imagine not choosing our own hair style, clothing and career path; much less not choosing our own spouse.
Sex, even “great” sex, is a normal part of life for married Christians; but, and here is the irony for our culture, great sex is the byproduct of Christ-like loving and giving in the context of a life-long relationship.
Feeling sexually attracted to someone you hardly know is certainly no way to determine if someone will make a good wife or husband.
