What the Bible says about John's Connection with Temple Worship
(From Forerunner Commentary)

Luke 1:5 From both parents, Zechariah his father and Elisabeth his mother, John was a Levite. He was from Aaron's line, yet not one acknowledgement is made regarding John having any tie at all with the already-installed system of Temple worship. John W.
