This series presents four essential aspects of Christian doctrine. In week 1, John talks about why the Scriptures are essential. In week 2, Rick discusses the Trinity; a vital, profound, and (yes!) usually confusing aspect of central Christian doctrine. In week 3, Ted takes a look at humanity and the fall of man from Adam's perspective. In week 4, John wraps up with a discussion of Grace: it's what sets Christianity apart from all other religions and philosophies.
