Here is a good read on SharperIron about Dr. Earnest Pickering by Kevin Mungons. Very interesting "stuff". There is a new edition of his classic book "Biblical Separation", which IMO is the best treatment of the issue. It had a profound influence on shaping my belief in the importance of separation. I would encourage everyone- both non-separatist and separatist to read this book. Dr. Pickering was a thinking fundamentalist of his day. I am glad the Lord blessed me with the privilege of hearing him preach before he passed on to presence of Christ.
