Among the reasons given by several Reformed Church in America churches in the midwestern US when leaving the denomination are issues with the Belhar Confession, a document emphasizing reconciliation and justice in the context of race and poverty. Kevin DeYoung, the pastor of University Reformed Church in Michigan, wrote:
Let me simply say at this point that our reason for seeking to leave the RCA is not one thing, but many things. From the adoption of the Belhar Confession, to the removal of the conscience clauses related to women’s ordination, to the growing acceptance of homosexual practice in the denomination, we believe the RCA has changed significantly in the last several years.

After giving the confession a cursory read, I didn't notice anything particularly problematic in it with respect to conservative Reformed theology. But it sounds as though I might have missed something. What is an overview of the several most significant objections to the Belhar Confession given by the conservatives leaving the RCA in recent years?
