Monday and Tuesday I had
the privilege of attending the 2010 Hughey Lectures here at IBTS that were given by the Revd Dr Peter Morden of Spuregon's College. IBTS and a number of faculty members at Spuregon's has a close working relationship.
His lectures were very enjoyable and I learned much. For those on the board who admire Spurgeon you migh like to purchase a copy of Dr. Morden's book, The People's Preacher.
Spurgeon is greatly responsible for my theology.
I was a free will baptist who believed that men were plenty good and that they determined their own eternal destiny, etc...
One cannot read the christocentric Prince of Preachers and remain an Arminian, man centered person, long under his tutelage.
The scholar on Spurgeon said in his lectures that Spurgeon incorporated both Calvinist and Armenian beliefs in his theology. He gave a quote from Spurgeon that went something like, "There are the elect and I am going out to make others the elect also."
I found it interesting that Spuregon found ways to incorporate both belief systems into his theology. Now, I am not an expert on Spuregon and cannot give you more information on this. Perhaps the book mentioned in OP does so. I have not had a chance to read the book.
Several years ago there was another scholar, I wish I could remember his name, here who is known as a strong Calvinist. While talking to him I said that there are truths in both belief systems and the problem is that we with finite minds have a hard time seeing the truths in both. He agreed with me saying, "Yes, that is true."
Spurgeon certainly did not incorporate both belief systems into his theology.He was a strong Calvinist -- not to the degree of someone like John Gill -- but an ardent Calvinist. Some folks get confused when they realize that CHS gave unfettered proclamations of the Gospel and urged his listeners to turn to Christ. That's not being Arminian -- that's just being biblical.
