What grieves me is when brothers can mention a name of a proment brother who was used of the Lord and in a few statements discredit and malign their name. I am not accusing the brother that started this post for directly doing that, but in the past this has happened quite a few times.
I would really encourage brothers and sisters to read the history of brethren such as George Fox, I personally read through most of the collected Works of George Fox a 9 volume set with over 200 pages. I believe he was a prophet in england where reformed principles and ecclesiastical religion where at a height yet at the same time there was a dearth of the holy Spirit's working and men where doing ministry for mammon. George Fox preached heavily against serving Christ for coins and ware. Such admonitions are needed also in our day of professional preachers in North America.
Here is a pensketch of the life of George Fox that I wrote and encourage all saints on this site to read it: https://www.sermonindex.net/modules/articles/index.php?view=article&aid=27157
John Bunyan though opposed the quakers early on, once he spent time in jail with some of these brethren realized they were that in fact, brethren!
Paul Cain though not associated well in our day God did use at some points in his ministry, I would not commend his ministry either especially to the fact of how the vineyard and charismatic movement has worked out in the last 20 years.
As for Charles Finney, those who have been more mature in their walk with Christ though opposing some of the doctrinal stands have commended Finney as a man of God and used powerfully of God.
God's ways are above our ways and His thoughts above our thoughts.
