The church is currently standing on the edge of a precipice, and in spite of the dangers it faces, it still listens to teachers of false doctrines and heretics, as if they are brothers of the gospel.
The church has indeed lost its core beliefs, and indeed does not believe that they are that important. If the church believed that its core doctrines were really important, it would have stood its ground against the heretics and false teachers of our day.
James McDonald tackles McLaren in a blog post:
"I do not view Brian as an ‘erring weaker brother,’ worthy of sympathy or olive branches, but rather as a dangerous false teacher who repackages mainline liberal theology. (Have the past 50 years not been adequate to see how liberal theology empties churches and damns souls?)
"More dangerous still is that McLaren packages his false teaching and denials of Scripture as solutions to some of the excesses currently plaguing evangelicalism—the danger being his winning over of young people who have legitimate complaints about the current church, but who lack the discernment to see that his solutions are often unbiblical even when his critiques are fair."
