The Reformed Church of America-- a small group of reformed believers compared to, say, the Presbyterians-- has decided to adopt a new confession of faith, in addition to their main one from the Reformation. It is called The Belhar Confession, and it is a wonderfully prophetic document created in South Africa during apartheid. You can read it here:
The Belhar Confession
It is a wonderful piece of theology, declaring the unity of the church and so denies the separation of church members based on race or any other reason. The summary statement is:
"Therefore, we reject any ideology which would legitimate forms of injustice and any doctrine which is unwilling to resist such an ideology in the name of the gospel."
