“Oh, that you would rend the heavens and come down, that the mountains would tremble before you!” (Isaiah 64:1)
Oh, that you would rend the heavens and come down, that the mountains would tremble before you! As when fire sets twigs ablaze and causes water to boil, come down to make your name known to your enemies and cause the nations to quake before you! You come to the help of those who gladly do right, who remember your ways. But we have all become like one who is unclean, and all our righteous acts are like filthy rags; we all shrivel up like a leaf, and like the wind our sins sweep us away. Yet you, LORD, are our Father. We are the clay, you are the potter; we are all the work of your hand. Do not be angry beyond measure, LORD; do not remember our sins forever.
The Catechism identifies the petition rend the heavens and come down as the prayer of the whole Old Testament awaiting the Incarnation, the longing for God to break through the distance between heaven and earth (CCC 2584).
Brothers and sisters, you are our Father; we are the clay, you are the potter; we are the work of your hand. When the prayer rises from the awareness of complete unworthiness, our righteous acts are like filthy rags, the only ground left to stand on is the Father's love and the potter's investment. You made us. Do not abandon the work of your hands.
Lord God, rend the heavens and come down. We are the clay and you are the potter. Do not abandon the work of your hands. Through Christ our Lord. Amen.
