The waxing and waning of justification

The following words were first published 145 years ago. They may just as well have been written in the last thirteen years:

When more lax and unsound views of doctrine began to prevail in the Protestant churches, some of their divines lost their sense of the magnitude of the Romish errors upon the subject of justification, and began to make admissions, that the differences between them and the Romanists upon this point were not so vital as the Reformers had supposed them to be; and the Romanists, ever on the watch to take advantage of anything that seems fitted to promote the interests of their church, were not slow to avail themselves of these concessions.
