Isaiah 63:1
1Who is this who comes from Edom, with dyed garments from Bozrah? Who is this who is glorious in his clothing, marching in the greatness of his strength? “It is I who speak in righteousness, mighty to save.”
Wesley: the church asks with admiration who appears in this habit. Edom is Idumea, where Esau dwelt; it is put for all the enemies of the church. Bozrah is Edom’s capital—Edom meaning red, Bozrah a vintage. Here Christ gives an answer: he will faithfully perform what he hath promised, and truly execute justice. Mighty—I have power to accomplish salvation.
The One who comes is Christ, Savior who also judges. Edom first; then all the church’s enemies. Shared ground: he is mighty to save.
Calvin: this chapter has been violently distorted as if it related to Christ wet with his own blood on the cross. The Prophet speaks of God himself. The Lord comes forth with red garments that all may know he is their protector and avenger. Judgment on the Edomites shows the Church is the object of his care. The Lord himself replies: I speak justly; I claim no ordinary power to save.
God himself, not a crucified figure in this verse. Edom’s cruelty is punished. Same Speaker who is mighty to save; the fork is whether the crimson is Christ’s passion or the Lord’s slaughter of persecutors.
Key contrast Arminians hear Christ answering the church: he comes from Edom as Savior who also judges the church’s enemies. Reformed commentators hear God himself as the Church’s protector and avenger—Calvin refuses to make the crimson the Savior’s own blood on the cross. Shared ground: the Speaker is mighty to save, and Edom does not escape.
