Morgan Edwards

Here is a link to an article by Buddy Shurden at Mercer University:

Edwards is an important early American Baptist leader, as you quote; or as Howard R. Stewart called him: "...the outstanding American Baptist leader of the eighteenth century, simply because of being the primary contributor and motivator in more areas of Baptist church life than any other person."

Online in addition to what Joseph posted above:

Besides whatever you might find online, two important books about him are:

McKibbens, Thomas R., Jr., and Kenneth L. Smith. The Life and Works of Morgan Edwards. New York: Arno Press, 1980.
This can be found on The Baptist History Collection CD-ROM - Version 1.0, which is a great buy.

Stewart, Howard R. A dazzling enigma: the story of Morgan Edwards. Lanham, MD: University Press of America, 1995.

If there is a Baptist seminary/college/university anywhere nearby, you can probably find those two, plus Edwards' two volumes, Materials towards a history of the Baptists. Something much harder to come by is Edwards' Customs of Primitive Churches...

A few interesting things:
1. His unusual eschatological ideas (at least for his day) have become popular with Baptist pre-tribulation rapturists as a way around the accusations of its Darby/Irving origins.

2. Two things that possibly hindered his usefulness in his own day were (a) he was one of few (if any) Baptist "Tories"; it seems he possibly feared American Protestantism could become a worse persecutor of Baptists than the English; and (b) his premonition that he would die in 1770 and his subsequent resignation of the Baptist church at Philadelphia. (See the Brown University link above.)

 

McClintock and Strong's "Cyclopedia of Biblical, Theological and Ecclesiastical Literature" has this about Morgan Edwards:

Edwards, Morgan
a Baptist minister, was born in Trevethin parish, Wales, May 9, 1722. He
commenced preaching in 1738, supplied for seven years a small
congregation in Boston, Lincolnshire, and thence removed to Cork,
Ireland, where he was pastor for nine years. After spending one year more
at Rye, in Sussex, he emigrated to America, and in May, 1761, became
pastor of the Baptist Church in Philadelphia. In 1772 he removed to
Newark, Delaware, and preached to several vacant churches until the
commencement of the Revolution. After the war he delivered lectures on
divinity in Philadelphia and other parts of Pennsylvania, as well as in New
Jersey, Delaware, and New England. He died January 28, 1795. Besides
various manuscripts, he left behind him forty-two volumes of sermons. He
published a number of occasional sermons, addresses, pamphlets, etc. —​

I hope this helps.

Every blessing.
