(27) And the seventh angel sounded; and there were great voices in heaven, saying, (28) The kingdoms of this world are become [the kingdoms] of our Lord, and of his Christ; and he shall reign for ever and ever.
(27) Of whose sounding the trumpet Christ expressly foretold in (Revelation 10:7) and this is the second part of this chapter, containing a general history of the Christian Church, from the time of Boniface to the consummation of the victory declared by voice from heaven. In this history there are three branches: a preparation by the sound of the angels trumpet: a narration by the voice of heavenly angels and elders and a confirmation by sign.
(28) The narration has two parts: an acclamation of the heavenly creatures in this verse, and both an adoration by all the elders in (Revelation 11:16) and also a thanksgiving in (Revelation 11:17-18). The sense of the acclamation is, "Now the Lord has entered his kingdom and has restored his church in which most mightily recovered from the profanation of the Gentiles, he may glorify himself." Namely that, which the Lord ordained when he first ordained his Church, that the faith of the saints does now behold as accomplished.
