Son of Zechariah (a priest) and Elizabeth (a descendant of Aaron). Born into the priestly aristocracy, but chose the desert. He was a miracle baby, born to elderly parents, filled with the Spirit from the womb.
Like Samson and Samuel, he was a Nazirite from birth—no wine, no haircuts. He was set apart for holiness. He wore camel's hair and ate locusts and wild honey, embodying the return to the wild, untamed God of Elijah.
He was formed by Solitude. "He lived in the wilderness until he appeared publicly to Israel" (Luke 1:80). He grew up away from the corruption of the Temple system he would later critique.
