Can Christians be humanists and moralists?

[Mudhammam]

The question is not whether Christians can act moral or not, as they undoubtedly can, but is it also possible for a person who consistently derives their sense of morality from a book as anti-humanistic as the Bible (or if you're Muslim, the Qur'an) to actually be a moralist?--to ponder deeply the difficult moral dilemmas or social conflicts (sorry but you can't apply Jesus' few moral insights, such as the Golden Rule, to the majority of situations this might include) that often throw themselves at humanity--and be relied upon to arrive at sensible, rational, compassionate, and commendable moral convictions?

If any Christian finds my question comically condescending, well, how does it feel to have the tables turned?
