 This is what God did in the person of the Christ child born in Bethlehem's manger. God brings two realms together in the manger. On the one hand, a gift from earth born of the Virgin Mary, and on the other, a gift from heaven, fully divine, holy, and eternal with no beginning and no end. The Christ child is perfect in both respects, with no change in his divinity and no decrease or reduction in his humanity.
