He pointed them to to the rooms off the hallway, what he described as various denominations. This is because as believers study their Bibles they will develop convictions that move them beyond the minimal commitments of basic Christianity. The rooms represent different layers of shared beliefs that culminate in the kinds of nuances that distinguish Pentecostals from Presbyterians, and Lutherans from Baptists.
C.S. Lewis has led generations through the wardrobe and into the magical land of talking Fauns, lampposts, and the benevolent lion. But Lewis led just as many—likely more—into a far more powerful place, a hallway. Yet Lewis made it clear, he didn’t desire for any of us to stay there.
This is what C.S. Lewis had in mind when he talked about the hallway in his influential work Mere Christianity. The hallway represents the entry point into the Christian faith. The hallway can be well summarized by historic Christian statements, like the Apostle’s Creed. The hallway represents those basic things every Christian must believe, those unifying and foundational truths at the heart of Christian faith.
As great as this hallway is, however, Lewis didn’t want people to stay there. He pointed them to to the rooms off the hallway, what he described as various denominations. This is because as believers study their Bibles they will develop convictions that move them beyond the minimal commitments of basic Christianity.
