The headline is slightly click-bait-y. Greg Epstein is a Humanist. So while it’s correct to say that he himself does not believe in God, and is therefore an atheist, it shouldn’t necessarily be interpreted as “anti” theism (although often atheists get way too bad of a reputation anyway). I think this is an excellent choice and if you don’t read the article you should know he was selected by his peers, who are believers.
