Augustine has his own rendition of what we might call “authenticity.” Like Heidegger’s version, it involves answering a call, hearkening to an appeal, responding to a summons to become who I’m made to be. But that call doesn’t come from an echo chamber; it comes from the One who made me, a “friend who is closer than a brother,” who laid his life down for his friends. And who calls to me through others, through friends.
