I'm a sucker for lists: the 400 richest Americans, the 100 most beautiful people, the 100 greatest rock singers, five things you didn't know about collard greens.
So when it was suggested I compile a list of notable people of faith, I immediately was in.
I started reading about various pastors and theologians and modern-day saints and studying previously compiled lists.
I ended up with not just one, but three lists of my own.
Before you read them, let me offer several disclaimers.
First, mainly my lists revolve around Christians. That's not a matter of prejudice, but of ignorance. As a Christian minister, I'm way more familiar with leaders of my own faith. I mean no offense, and I hope none is taken.
Second, even my two Christian lists aren't meant to be definitive, but simply to fuel discussion. I'm certain as soon as this column is published, I'll slap myself upside the head and say, "How could I have forgotten (fill in the blank)?"
Third, these aren't necessarily people I agree with. They're people who have remained faithful to their beliefs — sometimes despite criticism or intense danger — and whose achievements have widely influenced others.
Fourth, the entries, although numbered, are not in order of importance, except for Pope Francis. Since he serves as leader of the largest religious denomination, he's likely the most influential Christian alive, and thus is entry No. 1.
Finally, in the initial list, I've included a married couple, Rick and Kay Warren, counting them as one entry because they minister together.
