"Christian" Samurai"?

It seems like people want to syncretize just about everything with the Christian faith. The latest thing that has come down the pike is the book "The Way of the Christian Samurai," and rest assured it will be one more mine in the minefields known as "Christian" book stores. It is another attempt to blend Eastern religous practices into Christianity in subtle ways. Whatever happened to "His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence"? (2 Peter. 1:3 ESV) Has the Bible become insufficient for our spiritual education? The Berean Call has a very good article about this new book at http://www.thebereancall.org/node/6297
