C. S. Lewis may seem like an odd subject for study when it comes to the theology and practice of worship. He was neither a clergyman nor a professional theologian. And though he wrote wisely and winsomely on a wide range of subjects related to the Christian life, he devoted relatively little attention to ecclesiology, liturgy, music, and corporate worship. Nevertheless, the broad outlines of his thinking on the subject of worship can be reconstructed from his occasional essays and private letters. In this post I will seek to demonstrate that Lewis is a valuable, if neglected, voice in discussions about worship and that coming to terms with his perspective will be instructive for all of us, even if we are not fully persuaded by all of his presuppositions and arguments. I will first explore Lewis’s understanding of praise, followed by a survey of his thoughts on the corporate nature of worship, including church music, liturgy, and the sacraments. I will then conclude with a brief analysis.
