Pilgrim
If he was correctly interpreting Lewis, then I think he gave an accurate portrayal of his concerns. Not sure I need to say anything more on that front.
I will say however, like yourself I have some serious concerns about the whole "New Calvinist" movement. Though I must say, that a few in the movement such as Dr. Albert Mohler and Mark Dever, I have benefited from on the past and can't understand why they identify with the movement.
Especially them both being Cessationists.
But then again I have benefited from JI Packer, but I now read him with a lot of discernment.
