To me who am but black, cold charcoal
grant, O Lord,
that by the fire of Pentecost,
I may be set ablaze.
after St. John of Damascus, c. 675 – 749, Syrian monk
I baptize you with water for repentance, but he who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire. – John the Baptist
