Marvin,
I could almost feel the struggle in your post and greatly enjoyed you sharing your thoughts on your crisis of conscience.
The error is taught with frequency in private and public settings arranged by the religion. The significance reaches to the point that, in some circumstances, premature death could result from abiding by the error.
Ask yourself this question: Would I act any differently if I was talking about a college as opposed to a religion? Both are institutions of knowledge and ideologies. The only difference IMO are the stakes. Just because the stakes have been raised should you act differently?
If a university observed policies that resulted in the "premature deaths" of students what would you do? Certainly virtue may even demand that you stay and assist your classmates to change the policies and help save lives. But what if the administration was simply a totalitarian regime that met all disagreement with either forced recanting (lying) or expulsion? What chance of reform would there actually be? What does history teach us about negotiating with terroristic authority?
Of course, if your staying was part of a well thought plan to help other classmates escape the danger, that is an entirely different story. However, if self deception is employed, imagining a result with no chance of success, then how can that possibly resemble anything having to do with honor?
Certainly many Germans deceived themselves during WW II and the cry from some officers, "I was only following orders" that resulted in the "premature deaths" of innocent people didn't hold up in a court of law. During that dark time in history, in retrospect many people suffered intense guilt and a loss of dignity for not doing something. Though admittedly the options were few.
Just because religions are constitutionally exempt from the same intensity of prosecution that may be applied to individuals, institutions, and governments, does that releive a moral obligation to love your neighbor as yourself, especially if claiming a Christian alligiance? How can a person sleep well and look at themself in the mirror knowing that at that very moment your neighbor and spiritual kin may be needlessly dying due to ignorance and domination while you cling to credulity?
I make no personal judgements here. You are the one with the knowledge of your inner motivations. My thoughts above are simply my opinions.
Good luck with your current conscience crisis. And, make no mistake about it, it is also a crisis of honor, virtue and dignity as well. It may, in all liklihood be one of the greatest tests of your character you will ever face.
