Is anyone else upset about this book Oprah is promoting A Course on Miracles ??

I see so many "Christians" saying how great this book is, but it is obviously the work of the devil. How can anyone claim to be Christian and promote a book that clearly denounces that Jesus Christ is the only way to salvation ?? This book is definitly as sign of the times.....a year long course to brain wash you into thinking there is no sin and your salvation is up to you....THIS IS CRAZY.
