Every Christian must be a theologian. In a variety of ways, this is something I tell my church often. And the looks I get from some surprised souls are the evidence that I have not yet adequately communicated that the purposeful theological study of God by lay people is important.
Many times the confused responses come from a misunderstanding of what is meant in this context by theology. So I tell my church what I don’t mean. When I say every Christian must be a theologian, I don’t mean that every Christian must be an academic or that every Christian must be a scholar or that every Christian must work hard at giving the impression of being a know-it-all. We all basically understand what is meant in the biblical warning that “knowledge puffs up” (1 Cor. 8:1). Nobody likes an egghead.
But the answer to formal scholasticism or dry intellectualism is not a neglect of theological study. Laypeople have no biblical warrant to leave the duty of doctrine up to pastors and professors alone. Therefore, I remind my church that theology—coming from the Greek words theos (God) and logos (word)—simply means “the knowledge (or study) of God.” If you’re a Christian, you must by definition know God. Christians are disciples of Jesus; they are student-followers of Jesus. The longer we follow Him, the more we learn about Him and, consequently, the more deeply we come to know Him.
There are at least three primary reasons why every Christian ought to be a theologian.
