Qumran Teacher of Righteousness; 4Q521 Messianic Apocalypse
The Teacher of Righteousness was received as an inspired interpreter who unsealed the prophets for a covenant remnant. 4Q521 expects a coming figure at whose time the dead are raised and good news is preached to the poor.
Jews who loved scripture still hungered for a living interpreter and a last-days messenger. Sola scriptura as the death of living prophets is a late Western move. The Restoration returns to Amos, to Ephesians 4, and to a church that is not headless.
