Friends, the mountain is a great image throughout the Bible. It is the place where we go up and where God comes down to meet us. Today’s first reading from Isaiah orients us to three holy mountains of the Lord: first, the historical Mount Zion; second, its fulfillment in the heavenly Mount Zion; and third, a sort of “middle mountain” of the Mass, where we raise our minds and hearts to God, who comes to gather us, to speak his word, and to feed us.
