By these words, as they were sent from the Father out of heaven in thunder-form, the race of men was enlightened: they apprehended the difference between the Creator and the creature, between the King and the soldier (subject), between the Worker and the work; and being strengthened in faith, they drew near through the baptism of John to Christ, our true God, who baptizes with the Spirit and with fire. To Him be glory, and to the Father, and to the most holy and quickening Spirit, now and ever, and unto the ages of the ages. Amen.
