Restoreth all things (apokatistanei panta). This late double compound verb, usual form apokaqisthmi in the papyri, is Christ's description of the Baptist as the promised Elijah and Forerunner of the Messiah. See on Matthew 17:10-13. The disciples had not till now understood that the Baptist fulfilled the prophecy in Malachi 3:5 f. They had just seen Elijah on the mountain, but Jesus as Messiah preceded this coming of Elijah. But Jesus patiently enlightens his dull pupils as they argue about the exegesis of the scribes.
