“You brood of vipers,” excoriates John the Baptist in what may well be the most politically incorrect Advent sermon ever delivered. John simply doesn’t fit the season. “Deck the hall with boughs of holly / ’Tis the season to be jolly.” There’s nothing jolly about John. With a garment of camel’s hair and a leather belt around his waist, he looks the part of that unrelenting, rigid prophet of doom Elijah the Tishbite, who wore virtually the same attire (cf. 2 Kgs. 1:8).
