There is a lot of anxious clamor out there over Pope Francis’s pending encyclical on climate change. Though some outlets have reported leaked passages from the document, I plan to wait for the official version before offering any substantive comments. It could be that the encyclical will say many theologically sound things, and certainly all Catholics are called to take the Pope’s words with the utmost seriousness. And while I imagine that there are many in the Vatican, including our Holy Father himself, who are a bit bashful about admitting this, when the Vicar of Christ speaks, the whole world ought to listen. For Francis is not just “some bishop,” nor is he just the head of “some religious body”; he is the successor of St. Peter, the lowly but steadfast fisherman who was handed the Keys to the Kingdom by God Incarnate, the Second Person of the Holy Trinity, our Lord and Savior Jesus Christ.
