The historic teachings of four major Christian traditions--Eastern Orthodoxy, Roman Catholicism, Reformation and Union Churches, and Evangelical and Free churches--are set forth here in a comparative framework. Following a brief historical introduction of each tradition, Ted Campbell provides an extensive overview of the tradition's beliefs on religious authority, God and Christ, human nature and salvation, and church, ministry, and the sacraments. He concludes by considering whether a definable core of Christian teachings cuts across denominational and confessional boundaries.
Surprised me by how readable it is, and fascinated I was in the topic. If you're curious about the development of the church, how and why it spit along the way in different branches, and the beliefs of each id highly recommend tho book. I rented it for my class but plan on purchasing it for my collection.
