Attached is a PDF version of my full article, and here's a summary...
The Belhar Confession should be adopted by the CRCNA as a declaration or testimony, not as a Form of Unity equal to the Heidelberg Catechism, Belgic Confession, and Canons of Dordt, our basic doctrinal standards. There are several decisive reasons.
The Belhar should not be adopted as a Form of Unity because it almost completely lacks the content of a doctrinal standard: It does not state the Gospel or summarize the Reformed Christian faith. More problematic, if taken on its own terms, it is ambiguous and misleading about the Gospel, central Christian doctrines, and social ethics. In fact it is widely used in ecumenical circles to promote progressive (“liberal”) theologies and social agendas. Thus adopting BC as a confession would diminish the doctrinal soundness, denominational unity, and ecumenical integrity of CRCNA.
However, if it is subordinate to and interpreted according to the Three Forms, then these problems do not arise. In that case, there are important biblical, historical, contextual, denominational, and ecumenical reasons for affirming BC as an official declaration or testimony about the Gospel’s implications for racial reconciliation and social justice.
