I have been thinking a lot about divisions among Christians, and how to think about them in a way that honors God. I think Lewis is spot on.
I found this quote in a wonderful book I admired and was then given, The Quotable Lewis, Martindale and Root, 1989, included in the section titled “Church: Divisions.”

There indeed both your and ours [Catholic and Protestant] “know not by what Spirit they are led.” They take lack of charity for zeal and mutual ignorance for orthodoxy.
I think almost all the crimes which Christians have perpetrated against each other arise from this, that religion is confused with politics. For, above all other spheres of human life, the Devil claims politics for his own, as almost the citadel of his power. Let us, however, with mutual prayers pray with all our power for that charity which “covers a multitude of sins.”
