The Battle for Sovereign Grace in the Covenant recounts much of the gripping history of the schism of 1953 within the Protestant Reformed Churches (PRC), the culmination of the hard fought battle for sovereign grace in the covenant. The book includes new, important details that have not been previously published and also provides the history of the controversial adoption by the PRCA of the Declaration of Principles, the document that in some ways occasioned the schism of 1953. In the appendices of the book, Engelsma gives a brief, valuable commentary on the Declaration, the first commentary to be written.
