I thank you sincerely for providing that great quote!
Glad you like it, but it is nothing new, or contrary to sole fide such as Puritans understood it.
In Puritan Protestantism there was often a tendency to make the way to the cross too narrow, perhaps in reaction against the Antinomian controversy, and as described in an account (http://www.the-highway.com/Early_American_Bauckham.html) of Puritans during the early American period,
“They had, like most preachers of the Gospel, a certain difficulty in determining what we might call the ‘conversion level’, the level of difficulty above which the preacher may be said to be erecting barriers to the Gospel and below which he may be said to be encouraging men to enter too easily into a mere delusion of salvation. Contemporary critics, however, agree that the New England pastors set the level high. Nathaniel Ward, who was step-son to Richard Rogers and a distinguished Puritan preacher himself, is recorded as responding to Thomas Hooker’s sermons on preparation for receiving Christ in conversion with, ‘Mr. Hooker, you make as good Christians before men are in Christ as ever they are after’, and wishing, ‘Would I were but as good a Christian now as you make men while they are preparing for Christ.’”
