Here are, according to Roger Olson, the ‘hallmarks’ of modern liberal theology:
1) A tendency to reduce the Bible to “the Christian classic” that is “inspired” insofar as it is inspiring;
2) A tendency to reduce Christianity itself to ethics such that doctrine is an expression of collective opinion always open to revision in light of changing cultural conditions;
3) A tendency to embrace and promote individualism in spirituality and doctrine while insisting on certain controversial ethical positions as matters of justice and therefore beyond debate;
4) A tendency to deny miracles or “demythologize” them so that belief in no miracle is essential to authentic Christian existence;
5) A tendency to emphasize the immanence of God over God’s transcendence;
6) A tendency to believe in the essential goodness of humanity and to deny hell except as inauthentic existence in this life;
7) A tendency to interpret Jesus as different from other humans only in degree (e.g., more spiritually and ethically advanced) and not in kind;
8) A tendency to promote authentic Christian existence as a life of love only without judgment (except of “injustice”).
NOTE: In case you wonder if you are truly a liberal. Some think they are liberal (often because of the stupidity displayed by some self-described conservatives) and they are not really, while others think they are not, when if fact they are. Roger Olson might help solve this dilemma, at least in part.
