There are some reference tools that are just helpful to have on the shelf, ready to access at a moment’s notice. One of those resources that pastors will find helpful is The Thiselton Companion to Christian Theology (Wm B Eerdmans), an 860-page volume from the pen of British theologian Anthony Thiselton. With some 600 articles on an array of theological topics and personalities from Abba to Zwingli, church leaders will find this a useful tool for quick reference or to do a self-directed theology refresher class, reading a few articles each day.
