Realism is about truth based in the real experiences of life. Our experiences are the very contexts that we understand and bring meaning into our lives. Those who live in different situations think differently about "truth".
Truth is survival to those who live in poverty and disease, whereas truth is liberation for those who live under oppressive regimes. Truth is about reality, life's situatedness, and personhood. If truth is disconnected to what we experience, or our individuality, then there is cognitive disconnect from what is being touted as "universal truth".
When David ate of the shewbread in the Scriptures, he was not reprimanded, because his need for sustenence was greater than his need for the "holy". Traditionalists condemned him, but Jesus did not. Compassion looks on others in thier situatedness and does not judge, but seeks to help. On the other hand, understanding that our helpfulness can also be short-sighted unless we acknowledge that each of us is different and the differences of our experiences and understanding will always limit how much we can help.
Theology "speaks for God" in traditionalists circles, but, theology is really about "man speaking about God". We cannot attain to God's mind, or God's personhood, as we just cannot know. We only have models of experience and religious representations of God.
Some want to make absolute assertions about God and demand that others follow their suit. What transpires is tragically a "social convention" that is passed off as "God". And God's name is "used in vain" by promoting, and demanding that everyone see and experience the same thing, the same way. Apart from conformity, there is no "real salvation". I personally think this is idolatrous, for we cannot know but in part, and we certainly don't understand the "other", they way we need to.
Those who have closed minds concerning diversity/difference are doomed to oppress and stifle, while those who have no way of measurement, have no gauge, where values can even be discussed.
All of us have limited understanding and we base our understanding upon different authorities. Each authority is a limited one and we must humbly acknowledge that to one another in seeking after and commiting to "truth seeking understanding"...
