Looks like this Jesus guy was a bastard. Not the bad kind,though. This says his mom was set up for an arranged marriage but she got knocked up first. The guy she was supposed to marry, Joseph, instead of yelling "You fucking slut, etc.tm", he was going to go through with the marriage, and get just divorced on the down-low later.
But he had this big dream where the kid was born and grew up to be some kind of successful, so that made him decide to stick with it. Good for him; seems like a nice guy, kind of.
This book isn't so bad once it gets past that dumb genealogy. I notice it's the New International Version, which is lucky because if I had to wade through begats and thous and thys, it would be the Old Recycled Version.
