Standard Divines of the Puritan Period This reprint series began in 1861, when the
Library of English Poets was complete. It has been stated that behind the project were "both a respect for the Puritan divines and a larger cultural ambience that reflected a hunger to reproduce the past." In his closing address as
Moderator of the General Assembly for the Free Church of Scotland, Begg said Here let me very strongly urge the careful perusal of those noble works of the old Puritans published by my friend Mr. Nichol, and so ably edited by my friend the Rev. Thomas Smith. I know nothing more fitted to elevate the tone of our pulpit, next to a complete mastery of the Word of God, than an earnest study of the works of men so honoured of God, so mighty in the Scriptures, and in the spiritual anatomy of the human soul, as the Goodwins, Clarksons, Adamses, and Sibbses of ancient times. The series was supplemented by
Biblical commentaries, beginning with one by
Henry Airay. ==Family==
