James Dennison has added a second volume to the already noteworthy Reformed Confessions set he has edited. This set provides a wealth of confessional and creedal material from the 16th and 17th centuries. You can obtain this volume here. The first volume can be found here as well. You may be surprised to see where the Reformed faith arose during these years. We are already anticipating the third volume!
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
