Edersheim's book The Life and Times of Jesus the Messiah has been called "one of the best known and most important references on the life of Christ ever written." However, a lot has changed in the last century since he wrote his book (it has been over 130 years). N.T. Wright has mentioned how outdated Edersheim's material is. Most notably, the Dead Sea Scrolls and the Nag Hammadi library had not yet been discovered during Edersheim's lifetime. How do modern New Testament scholars (especially those who specialize in first-century second-temple-Judaism) view Edersheim's work (I've already linked to a brief quote by NT Wright but please expand on his perspective as this is only a brief comment)? Do any respected New Testament scholars consider Edersheim's work to still be authoritative?
Please note that this is not an attack on Edersheim himself. He was likely a great scholar who did the best he could with the material he had available. This question is about the current value and accuracy of a specific work of his.
