Mathew Henry was not a 5 point Calvinist. He was moderate at most. He was a non-conformist minister.
I use his commentary quite often and he most definitely believed in a general atonement.
G . E. Ladd(baptist), F. F. Bruce (brethren), Oliver B. Greene(baptist), Henry Ironside(brethren) , David H Stern (messianic jew), Spiros Zodihates ( greek scholar) .
All of these theologians are non-5 point calvinist and neither are they considered arminian.
John Wesley was a preacher and evangelist.
I would not personally have described him as a theologian, any more than I would so have described Whitefield or Spurgeon.
