One of the fun things about teaching church history is introducing my students to all kinds of technical theological terms that they should never (ever!!!) use in a sermon, but nevertheless probably need to know. I require students in all of my classes to purchase a copy of the Pocket Dictionary of Theological Terms and bring it with them to class. They are not allowed to ask me to define a term in class unless they have first consulted the Pocket Dictionary to see if it is included therein.
I recently discovered that Alister McGrath has a glossary of theological terms on his Wiley-Blackwell author’s page. For those of you who haven’t heard of McGrath, he is arguably one of the two or three best-known evangelical theologians in the English-speaking world. He has written dozens of book on systematic theology, historical theology, spirituality, the Reformation, C. S. Lewis, and the relationship between theology and science. He is a sharp cookie. If you want to learn more about McGrath’s thoughts on some of these topics, check out my colleague Jamie Dew’s book Science and Theology: An Assessment of Alister McGrath’s Critical Realist Perspective and SEBTS alum Larry McDonald’s book The Merging of Theology and Spirituality: An Examination of the Life and Work of Alister E. McGrath.
Even if you don’t want to learn more about McGrath’s thought, avail yourself of his super-helpful glossary of theological terms. Your friends will be impressed when you tell them that Hesychasm is “A tradition, especially associated with the eastern church, which places considerable emphasis upon the idea of “inner quietness” (Greek: hesychia) as a means of achieving a vision of God. It is particularly associated with writers such as Simeon the New Theologian and Gregory Palamas.” Don’t you feel more theologically astute already?
