Tobit was written in the 2nd Century BC describing events in Nineveh shortly after 722 B.C. That means that Tobit was not written by Tobit, but by someone living 500 years later. Would you trust a brand new book written by Martin Luther himself in the year 2000?
Tobit 1:15 states that Sennacherib was Shalmaneser’s son. This is incorrect since he was the son of Sargon II
Tobit implies that he was alive during the reign of Jeroboam I (about 930 B.C.), and at his death he was reported to be 117 years old. The math is off by over a hundred years since he describes events in 722 BC.
Tobit claims that almsgiving alone “will save you from death”. Paul states in Galatians 2:15, that man is justified (saved) “by faith in Christ and not by observing the law, because by observing the law no one will be justified.” In John 3:16, Jesus says that “whoever believes in him shall not perish but have eternal life.” So either Tobit is correct and Jesus and Paul are wrong, or Paul and Jesus are correct and Tobit is wrong. One of them is not inspired by God.
... Those are my thoughts on Tobit.
It's interesting how easily the historical critical method of analysing holy scripture is applied by Protestants to a book like Tobit but rejected by Evangelical for each and every one of the books that Protestants say are canonical.
Tobit could just as easily be a work written in cuneiform around 700 BC and preserved until translated into Hebrew in 200 BC by someone. ...
It is obvious that Moses did not write the Hebrew text of the Pentateuch because when Moses is alleged to have lived there was no Hebrew script. If anything were written by Moses in or around the time of the Exodus story then it was written in some script from Egypt or Babylon but there's not a scrap of evidence that such is the case. Similarly "Tobit" may have written in Cuneiform only to be translated into Hebrew script 500 years after the original. But there's no evidence for that, just as there's none for Moses writing anything or David writing the psalms, or Solomon writing Proverbs, Ecclesiastes and the Song of Solomon.
If available evidence is used to decide authorship of any part of the holy scriptures then Isaiah wasn't written in Isaiah's time, Daniel was not written in Daniel's time, Proverbs and the Song of Solomon were not written in Solomon's time nor the Psalms in David's time. The same applies to Jeremiah, Ezekiel, and the 12 minor Prophets. It is also true of the four canonical gospels, several of the letters attributed to saint Paul and to the letters of Peter, John, Jude, and James. They all have significant gaps between the first reliable evidence for their existence and the alleged time of writing.
What is sauce for the goose is also sauce for the gander, as it is said; thus the holy scriptures' canon is not decided by alleged scholarly research into when the parts of the scriptures were written. The canon of holy scripture was decided by people. For Catholics it was decided by Catholic Church councils in the late fourth century AD. For Jews and Protestants the Old Testament canon was decided by Jews some time after the sixth century AD and for Protestants the canon of the new testament was decided by Catholics in the late fourth century AD and affirmed by Protestants in the sixteenth century AD.
