I Don’t Believe in Christianity

I recently read in Jaroslav Pelikan’s excellent Jesus Through the Centuries a line from American scholar Arthur O. Lovejoy, who asserted, “The term ‘Christianity’ is not the name for any single unit of the type for which the historian of specific ideas looks.” Rather, the term describes “a series of facts which, taken as a whole, have almost nothing in common except the name”. At first I thought his statement was absurd, but the more I thought about it, the more I thought it was true. And that I did not believe in Christianity. Please let me explain.
