Authorship debate
| View | Position |
|---|---|
| Single Isaiah (traditional) | Mainstream evangelical + Jewish + Catholic + Orthodox tradition. NT consistently quotes "Isaiah" for material from all sections (Mat.3.3; Mat.4.14-16; Jhn.12.38-41; Acts 8:28-33; Rom.10.16) |
| Multiple Isaiahs (critical) | Critical OT scholarship since 19th century, based on historical references (Cyrus named in Isa.44-45 well before his time) + stylistic features + theological emphases |
| Conservative response | Predictive prophecy (naming Cyrus) consistent with conservative view of Scripture; stylistic + thematic differences within single author's lifetime + ministry |
This reference notes the debate; mainstream evangelical affirms single authorship; critical scholarship favors multiple. NT clearly treats Isaiah as unified.
