Have you come across any of this?

It's interesting and important to see the issues cropping up on the life of The Gospel Coalition. Real gospel ministry must involve real people, real doctrine, real politics and real challenges. 

The latest drama has been with Billy Graham's grandson, Tullian Tchividjian being asked to take his blog off the Gospel Coalition site. Kevin de Young has published a helpful roundup of blogs about the issue.

As far as I understand, it has to do with Tchividjian so emphasising grace that he has no doctrinal space left for the need for obediences to commands in the progressive sanctification of the Christian life.

This is a helpful extreme that warns against letting the 'gospel centred' thing mutate so much that it swallows up the full teaching of Scripture.
