David Watson, dean of United Theological Seminary, offers his answer to the question: What is a Liberal Christian?
Read the whole post at his site, but here is a taste:
Now, I don’t know any Christians who would say that they are against social justice. We may conceive of it differently from one another, but, generally speaking, we all believe that God offers to us a righteous, life-giving way of ordering our relationships. What sometimes gets lost in talk about social justice, however, is that, as Christians, we cannot know what social justice is apart from God’s self disclosure through Jesus Christ and the Holy Spirit. In other words, special divine revelation is necessary for us to know what social justice is. Additionally, the Christian life is not simply about emulating Jesus or abiding by his teachings (though these are important), but the transformative power of Jesus’ cross and resurrection mediated to us by the work of the Holy Spirit. In other words, a well-articulated understanding of the Trinitarian faith of the Church, and an experience of the Trinitarian economy of salvation, are necessary in order for us to reach a point at which we can talk about social justice as Christians.
