There are a variety of reasons for converting to a religion. What is your opinion of people who convert to Orthodoxy because they say "it works"? Maybe someone isn't sure that Orthodoxy is "the Church Jesus founded" or "the faith that established the universe" or whatever. Maybe they aren't even sure about certain doctrines that most would consider mandatory (though they aren't speaking out against these doctrines either). They say they convert because they were sick/hurt/suicidal/whatever, and that Orthodoxy helped them, changed them, gave their life meaning, etc. Maybe they say something like "I would have been dead had I not become Orthodox." What would you say to such a person?
