If I were an unbeliever, then I would absolutely consider the idea, but don't you think as a one who delcares to be a believer that a fictional genealogy would just cause one to doubt the whole thing? You aren't a believer, and so it's natural for you to doubt coming at it from that perspective. I am sure I would do the same if I didn't believe.
Where does the fiction end and the truth begin? Is Mary fictional, or Ruth? Was David real? Was Abraham? Was Daniel? Is it just Adam and Noah, or is Jacob also fictional? Partly historical and partly ficticious just means part truth and part lie. If part is a lie, then why bother at all because Jesus would simply be a liar, and the apostles too. The books we are talking about lead into Christ, and the Bible doesn't distinguish them as allegorical at all, but rather uses the lineage to point to Christ, our Salvation, as a real man born into our world. Those people, and those events, are full of promises of a Messiah to come, pictures of God, and shadows of things to come, and they are treated as literal throughout...historical. Why do you think that any of those persons mentioned in the geneology be fictional? Paul didn't treat these people and books as figurative. Jesus didn't. Early Christians didn't. Is there something in the texts that points to them being figurative in your mind? I don't see any logical basis for the figurative argument from the text. I was waiting for ken's position to be supported.
The Lord bless you, Eric.
