The problem they have is that though they Believe in the Word of God and though they Believe in Christ, they do not Believe Christ nor the Word of God.
Christ Tells (Commands) us to do something and people who claim to Believe in Him choose to do their own thing; the Word of God Reveals something and people who claim the Word of God as their only Authority, often ignore the Word.
How is the Virgin greeted by the angel? Is it the same as in other instances when a messenger of God greets other people, such as Zechariah? No. The Archangel Gabriel salutes the Virgin: ‘Hail.’
This salute is one that is very formal and granted only to heads of states (as far as I have come to understand); so of what state is the Virgin the head of?
Then we have the “visit.” At the moment that the Virgin greets her relative, Elizabeth, John the Baptist, all of 6 months of him, jump for joy in recognition of the Presence of God, his Lord. Almost simultaneously, Elizabeth, infused with the Holy Spirit, Calls the Virgin the mother of her Lord (God); not only that but she is amazed that the Virgin would extend herself to visit a mere servant of God!
The Holy Spirit, not being finished, prophesizes through the Virgin that all generations will Celebrate the Incarnation of the Word as they would honor the Virgin, Who, in humble Obedience, Believe in the Word of God!
Now about missing things; since Jesus hanged around for about three and one half years, during His Ministry, could He not have found a few good men (no, not US Marines)… a few good scribes to consolidate the various versions of Sacred Scriptures into one volume and dictate a comprehensive plan for the Church that would include the New Covenant’s Revelations as well as Church Doctrinal Practices, with all the bells and whistles included, so that man would not have to wonder in the dark?
…or didn’t He?
Maran atha!
Angel
