Birth of Christ was a personal scandal and a political powder keg, threatening Israel's very existence. This is the main theme of the Gospels. Few movies or pulpits pay attention to it. We begin to see why, in this (3/2/12) Episode.
About how Luke 'wraps' to Matthew: notice that where Matthew provides little detail, Luke provides much, and vice versa. Notice also, each author goes silent to witness something embarrassing. For example, it's embarrassingly obvious that Rome's most feared enemy, Persia, would seek to marry off someone in its royalty to another 'king of the Jews' -- when an old king often lay dying of 'worms'. So would Jerusalem get squished in-between? Or would civil war start? It was already brewing for other reasons.
To get a quick sense of that time, click the link below, select 'Page 103' and start reading from about page 100 through the end of the chapter. Smallwood's book is pretty typical of her scholarly circle, which debunks Bible. So she misses the importance of the magi -- which after all, Herod would have to silence, too.
But as it turns out, this Son of David was of questionable legitimacy. After all, Mary was about 36 when she gave birth, per her own dateline meter in the Magnificat, as a future episode will show. Who's gonna believe He was born of the Holy Spirit? Can't God make a married woman conceive supernaturally, instead? Why expect Israel to believe an OLD virgin -- even if she was disposyni, legitimate royalty from the House of David, next-in-line-for-the-throne? What, is God being politically-incorrect?
Yeah, and the fact people thought He was illegitimate, spared Him from kings who'd want to capture or manipulate Him... You don't see the pulpits or movies cover that angle, either. But clearly the Bible DOES cover it. Just the facts, ma'am. Leaving the obvious, in silence...
