I have often heard Mary spoken of as the ark of the New Covenant. Tonight at RCIA, I learned of a parallel between Mary and the original ark that I had not heard before.
"And David was afraid of the LORD that day; and he said, ‘How can the ark of the LORD come to me?’…And David danced before the LORD with all his might;" – 2 Samuel 6:9,14a
"And why is this granted me, that the mother of my Lord should come to me? For behold, when the voice of your greeting came to my ears, the babe in my womb leaped for joy. " – Luke 1:43-44
Interesting, ain’t it? Of course, the entire notion of the Immaculate Conception doesn’t (and couldn’t) hang on these verses, but I think they’re interesting nonetheless.
