I think I've listened to the first four of these now. It's been mostly Pastor Bob saying to Sidney something like "so you would agree with the teachings of Jesus, that it's wrong to kill your neighbor and take his stuff?"
He kept on taking basic moral questions and framing them as if they're unique to Christianity.
And does Pastor Bob really think that the fact that the writers of the gospels were able to cherry-pick bits out of the Old Testament and incorporate those into their stories, that this is somehow evidence for the divinity of Jesus? Really?
Also, I was surprised to hear Bob quote the Septuagint translation of the Hebrew word alma, into the Greek word for "virgin." I didn't know anyone would actually claim that Isiah meant a virgin when he told that a young woman would give birth. It's also clear that this story wasn't meant to be a future prophesy, but something that was to happen during the time of King Ahaz, hundreds of years before Jesus.
I knew that the writer of Matthew was making this link based on the translation error in the Septuagint, but I wasn't aware that anyone today would try to support this link.
