“Question & Answer”

Question:
What theological differences are there between 1 Isaiah and 2 Isaiah?
Answer:
Examples of the doctrinal differences they mention are that “Second Isaiah” does not mention the Messianic King or faithful remnant of Israel, but instead emphasizes the suffering Servant. Another is that God’s rule and uniqueness was also more emphasized in “Second Isaiah”.
1 Isaiah emphasizes the holiness of God {Holy, Holy, Holy is the Lord of hosts 6:3}
2 Isaiah stresses His everlastingness: “Who has performed and done this, calling the generations from the beginning? I, The Lord, the first, and with the last; I AM HE!” {41:4}
1 Isaiah pictures the coming of the Messianic King: And the government will be on His shoulder, and His name will be called “Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace'” {9:6}
2 Isaiah revolves about the idea of the Suffering Servant: He was despised and rejected by men; a man of sorrows, and aquainted with grief; and as one from whom men hide their faces He was despised, and we esteemed Him not” {53:3}.
The author of 1 Isaiah was himself called to be a prophet{“Whom shall I send? “Send me” 6:8}
In 2 Isaiah it is the community of Israel that is called to be a prophet “To the nations” {42:1}, whose function it is to establish “Justice on the earth” {42:4} and be “a light to the nations” {42:6; 49:6}.
