With Reformation Day rapidly approaching it seems appropriate to consider the origins of what we call the solas of the reformation (i.e. Sola Scriptura, Sola Gratia, Sola Fidei, Solus Christus, and Soli Deo Gloria). Scott Clark has a helpful post outlining the history of these five tennets of the Protestant Reformation. You can read it here. If anyone is able to contribute more to the historical development of Solus Christus and Soli Deo Gloria, feel free to do so in the comment section of this post.
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)
