Misinterpretations of Isaiah 66:21 often include seeing it as a complete replacement of Jewish priests by Gentiles, fueling supersessionist views that dismiss Israel's ongoing role; others apply it legalistically to modern church offices, claiming exclusive priestly authority for certain groups while ignoring the prophetic context of eschatological restoration; some spiritualize it away to negate any future literal fulfillment in the millennial kingdom, or misconstrue it as endorsing universal priesthood without regard for God's specific calling from all nations.
Isaiah 66:21
King James Version (1769)
21 And I will also take of them for priests and for Levites, saith the Lord.
In Isaiah 66:21, God declares His intention to select some from the Gentiles—those gathered from the nations—as priests and Levites, signifying the radical inclusion of non-Jews into the sacred roles of worship and service previously reserved for Israelites, fulfilling the vision of a new heavens and earth where God's glory draws all peoples into intimate fellowship, transcending ethnic barriers and establishing a universal priesthood under His sovereign choice.
