Let me start over...
In Revelation 11:15 who is the subject of βασιλεύσει?:
Revelation 11:15 καὶ ὁ ἕβδομος ἄγγελος ἐσάλπισεν καὶ ἐγένοντο φωναὶ μεγάλαι ἐν τῷ οὐρανῷ λέγοντες ἐγένετο ἡ βασιλεία τοῦ κόσμου τοῦ κυρίου ἡμῶν καὶ τοῦ Χριστοῦ αὐτοῦ καὶ βασιλεύσει εἰς τοὺς αἰῶνας τῶν αἰώνων
Sorry to have over-complicated the question. I'm pretty sure my mom dropped me on my head; recently.
Bill, you're making it much more complicated than it is. And the video really has nothing to do with your question. You can split the text into three parts - A quotation, the intro to the quotation, and a preliminary clause. The quote is "ἐγένετο ἡ βασιλεία τοῦ κόσμου τοῦ κυρίου ἡμῶν καὶ τοῦ Χριστοῦ αὐτοῦ καὶ βασιλεύσει εἰς τοὺς αἰῶνας τῶν αἰώνων.", the intro is "καὶ ἐγένοντο φωναὶ μεγάλαι ἐν τῷ οὐρανῷ λέγοντες . . .", and the preliminary clause is "καὶ ὁ ἕβδομος ἄγγελος ἐσάλπισεν"
"καὶ ὁ ἕβδομος ἄγγελος ἐσάλπισεν" = "and the seventh angel trumpeted" - ἐσάλπισεν could be he, she, or it - but we know it's "he" because of " ὁ ἄγγελος".
What the video discusses is the non-agreement of φωναὶ μεγάλαι with λέγοντες i.e. the sense is referring to the angels/martyrs/witnesses/whatever making the great noise - and they could be all masculine or mixed guys and gals - either way would call for λέγοντες. That's all the video was saying. And making a great to-do about something which is really not very important.
What you are bothering about is the last part of the text, which has nothing to do with either ἄγγελος or φωναὶ. βασιλεύσει = he/she/it will reign/rule, and when we look for the noun(s) we find both κυρίος and Χριστος. Ah - I think I see now what has confused you - is it the "our Lord" and "His Christ" ? - it's the same person, not two different people - the "His" must refer to God the Father. And before we wander off into Trinitarian or Arian or whatever debate, let's just leave it as an echo of Hebrew parallelism - two ways of saying the same thing, two ways of referring to the same person, who is the one who will rule. And remember - John (or whoever is the author) is at a loss for words all the way through Revelation, he's trying to express what is beyond words.
Just my two denarii
