Heresies and How to Avoid Them, edited by Ben Quash and Michael Ward

Ten top theologians, all practising Christians, tackle ten ancient heresies and show why the contemporary Church still needs to know about them. Christians need to remember what these great early heresies were and why they were ruled out, or else risk falling prey to their modern day manifestations. The book contains key scriptural passages relevant to each heresy, a glossary of terms, and summaries of historical Church documents in which these heresies were defined and outlawed.

This really is just like the book blurb describes it — reacquainting Christians with ancient heresies and how one might encounter them today. I was surprised to see that a tendency I really hate — to talk about the God of the Old Testament as a hateful deity and Jesus of the New Testament as correcting that OT god with his love and sweetness — is the ancient heresy of Marcionism. Aha! (The Trinity is three persons, ONE essence. As Jesus said, "Whoever has seen me has seen the Father.")

Anyway, some of the chapters are easier to understand than the others but all are good. Each begins with a quick summary of the heresy, followed by key scriptures which refute the errors. Each of the authors also took pains to point out that the heretics and their teachings were often well intentioned in desiring to clarify a misunderstanding about the faith. Often the heretics simply didn't go far enough in thinking things through and then dug their heels in when their theories were questioned and shown to be inadequate.

The generous attitude of the authors does not mean that they condone heresy. It does mean that they look upon it as "provocative stimuli, catalysts for energetic thought." Otherwise how can one counter it? That is how I have felt when encountering it, as I did very shortly after converting and innocently sashaying out to a bookstore to pick up books about Catholicism. I was quite surprised to see that there were a lot of divergent schools of thought about various topics in the Church. I quickly learned to educate myself in the why's and how's of the Church's dogma and doctrine so I could evaluate what I came across. Many such opportunities to dig deeper into our own faith are presented to us today and that "generous attitude" of one that I think is valuable to remember when we find ourselves confronted with heresy today.

The final chapter and the epilogue point out how dangerous heresy is and why orthodoxy is important. Both are excellent reminders of the importance that real truth makes to our relationship with God.
