Kevin, I read your writings on the link you provided.  I do not think that the "liberals," in the church are at all attempting to throw all morality aside and aiming for completely unprincipled lives.  Quite the opposite is true.  I think that most "liberals" and "conservatives" are attempting to look at the reality of conditions today. I think there is a problem in the labels of liberal and conservative.  I recall when Conservative meant the preservation of resources and accepting change but only slowly after evidence. Liberal meant to be much more quick about change.  Now days those that call themselves conservatives or orthodox are really reactionaries wishing to return to the past.  These reactionaries even label conservatives like myself as "liberals." The way you are using the word liberal is to call all "liberals" very much radicals.   I think the humility you seek would be to label Reactionaries and Radicals for what they are and move ahead as reasonable people of one faith.
