Should we be comparing Islam and Christianity, the Bible and the Quran?

The other week, I was talking with a friend of mine who is pastor of an evangelical congregation in Texas.

He was asking for my input on a multi-week series comparing different “world religions” with Christianity at his church.

Numerous, well-meaning pastors, lay leaders, and teachers like my friend have led such comparative studies in their own communities as a means to help Christians navigate contemporary religious pluralism. I even led a few of my own in my early days. While most of the leaders of these studies start with the intention to help their parishioners learn more about the world's religions, the way they go about it usually leads to nominally increased religious literacy. Even worse, these studies can exacerbate pre-existing prejudices or presuppositions about the religions they set out to better understand.

Which raises the question of whether there is any promise to comparing things like Christianity and Islam, the Quran and the Bible at all. The problem, I suggest, might lie in the very act of comparison itself.
