And whence did the disciples know this? He had already told them, He is Elias, which was for to come; but here, that he hath come; and again, that Elias cometh and will restore all things. But be not thou troubled, nor imagine that His statement wavers, though at one time He said, he will come, at another, he hath come. For all these things are true. Since when He saith, Elias indeed cometh, and will restore all things, He means Elias himself, and the conversion of the Jews which is then to take place; but when He saith, Which was for to come, He calls John, Elias, with regard to the manner of his administration. Yea, and so the prophets used to call every one of their approved kings, David; and the Jews, rulers of Sodom, and sons of Ethiopians; because of their ways. For as the other shall be forerunner of the second advent, so was this of the first. Chrysostom
I'm really not sure what you would think that St. Theophylact would be misinterpreting in St. John. Maybe I'm missing a subtlety in your argumentation here.
What you highlight in St. Theophylact are his statements that Elijah the Tishbite will come as a forerunner of the second coming, and that he will bring the Jewish people (at least all that are teachable) to faith in Christ.
St. John says that "the Tishbite comes before that other advent, which hath the judgment..."
This identifies him as a forerunner of the second coming of Christ and the last judgment.
He also says that the reason for his coming is specifically to "persuade the Jews to believe in Christ" and that by saying 'he shall retore all things" Christ means that Elijah the Tishbite "shall correct the unbelief of the Jews that are then in being."
The section you highlight in St. John's writings basically makes the point I have been explaining all along about the Orthodox view of these things:
When Christ says that 'Elias indeed cometh, and will restore all things,' He means Elias himself [i.e. the Tishbite -- the same Elijah who appears in the OT], and the conversion of the Jews which is then [i.e. in the last days, prior to the second coming] to take place;"
When Christ says 'Which was for to come, He calls John, Elias, with regard to the manner of his administration [i.e. he is an Elijah in his type of ministry and calling]."
Christ says that Elijah *will* come (i.e. the Tishbite) and that he *has* come (i.e. John the Baptist, who came with the same ministry, characteristics, and power as Elijah). One is literally Elijah the Tishbite (at the second coming), and one is "another Elijah" in a figurative sense.
Sts. Theophylact and John are saying exactly the same thing. Again, perhaps I'm missing a fine point that you are making. I think that at the root of Calvin's problem was the characteristically Protestant tendency to view prophecy in a single dimension. Prophecies occur in the OT, and then are checked off as they are fulfilled.
Orthodoxy just doesn't look at prophecy that way. When Christ is talking in the sections of the Gospels about the destruction of Jerusalem, we believe that he is in some cases referring only to the immediately coming destruction, in some places only to the tribulation and his second coming at the end of time, and in other places he is speaking simultaneously of events that will shortly take place *and* about events in the distant future. The Apocalypse speaks both of contemporary events and events at the end of time -- sometimes one, sometimes the other, much of the time both simultanteously.
This exercise we have gone through regarding Elijah is quite representative of general Orthodox understandings of Biblical prophecy.
