Throughout the preceding chapters, Lewis has been demonstrating what “Mere Christianity” is by showing first what the Law of Morality is and then how it functions in the Christian life. We looked at several virtues and what characterizes each of them. Now we turn to a bit of a different book. In Book IV, Lewis addresses more of the “Theology” of Christianity, beginning with the Trinity.
Right from the onset, Lewis draws attention to a mentality that continues today – people are not concerned with theology (the study of God); they just want a personal relationship with Jesus without another’s interference. Don’t give me doctrines, dogma, or principles. You believe what you want to believe, and I will believe what I want to believe. I just want the love of Jesus, and that’s enough for me. Many will say such things when it comes to discussions about theology.
Lewis uses the analogy of a map versus visiting particular places. Sometimes we underestimate the inherit value of a map, but Lewis says:
The map is admittedly only coloured paper; but there are two things you have to remember about it. In the first place, it is based on what hundreds and thousands of people have found out by sailing the real Atlantic… In the second place, if you want to go anywhere, the map is absolutely necessary (136).
Of course he is applying this analogy to the Bible and the importance of the Bible in the Christian life. Many who think regular, thoughtful, reading and engaging with others about the Scriptures often think of Christianity (and other religions) as a type of spirituality. For them, there are religious connotations tied to the reading and application of Scripture.
Lewis, when talking about theology, wants to distinguish between the Bios and Zoe. The bios is the temporal, fading part of life. It is the part that always results in death. The zoe is the opposite; it is the eternal aspect of spiritual life – where one spends all eternity in the presence of God.
Lewis attempts to explain the distinction by, in the previous paragraphs, discussing the difference between making and begetting. God makes man, but God cannot beget man; God can only beget Someone like Himself. God begets Christ. Man does not make man; man begets man.
Lewis is not a theologian and does not go in depth about the nature of the Trinity. He does, however, in his own style provide a helpful way to think about the Trinity’s beauty and complexity.
Before we go further, I would like to interject a few comments. The word “Trinity” does not appear in Scripture. It is a Latin word “trinotos” applied to the Bible’s teaching on the matter. The early church did not use such language, although they acknowledged the special relationship between the Father, Son, and Holy Spirit. It was in the Fourth Century that the church began using such language to describe the relationship between God the Father, God the Son, and God the Holy Spirit. Seventeen centuries later, it is a doctrine essential to the Christian faith.
Lewis explains the Trinity by using the example of a man saying his prayers by his bedside. “An ordinary simple Christian kneels down to say his prayers. He is trying to get into touch with God. But if he is a Christian he knows that what is prompting him to pray is also God: God, so to speak, inside of him. But he also knows that all his real knowledge of God comes through Christ, the Man who was God – that Christ is standing beside him, helping him to pray, praying for him (143). It is through this understanding that theology begins to make sense. As Lewis says, “Theology is, in a sense, experiential knowledge.”
I believe Lewis puts it well in the final paragraph of chapter two. Many people are fabricating religions and making their own systems of standards by the figments of their imaginations. Lewis says:
If Chrisitianity was something we were making up, of course we could make it easier. But it is not. We cannot compete, in simplicity, with people who are inventing religions. How could we? We are dealing with Fact. Of course anyone can be simple if he has no facts to bother about (145)
Questions to consider
*What do you think when you hear the word “Theology”?
*Lewis talks about Christian community as an “adequate instrument”. Do you have community in your life?
*Do you believe the Bible speaks about “Facts”?
*Is the Bible more than moral guidelines and helpful advice? Does it contain the truths of God essential for salvation?
