Gary has got you on this one Always.    If you expect the law to cover all 'Christians', then you chose to assume all Christians have identical religious guidance, or, have identical standards of personal conscience.   The facts are that they don't.   The diversity of behaviors on Christian have very little variance from the non-religious population, (my pastor would often say an 'unmeasurable amount of difference,' and say it with a touch of sadness to an audience who prefers to feel more righteous).

I would never enter a church again if I spent my time judging the faith of those who sit in the pew with my family.   For Christian church's who like to use the word 'truth,' they would be better served by saying they are the equals of the non-religious, not inherently superior by use of the 'Christian' label.  *Most of my moral choices are deeply rooted in my Christian faith, that does not mean they are the same as every other person labeled 'Christian'.
