"Will the one who contends with the Almighty correct him? Let him who accuses God answer him!" (Job 40:2)
The LORD challenges Job: will the one who contends with the Almighty correct him? Let him who accuses God answer him! Job answers: I am unworthy - how can I reply to you? I put my hand over my mouth. I spoke once but I have no answer - twice, but I will say no more. The LORD speaks again from the storm: would you discredit my justice? Would you condemn me to justify yourself? Do you have an arm like God's, and can your voice thunder like his? Look at Behemoth, which I made along with you; he feeds on grass like an ox. His tail sways like a cedar; the sinews of his thighs are close-knit. Can you haul in Leviathan with a fishhook or tie down its tongue with a rope? Any hope of subduing it is false; the mere sight of it is overpowering.
The Catechism identifies Job's silence before God as the fruit of the encounter with the Holy - not the silence of despair but the silence of the creature before the Creator who has revealed himself (CCC 2100).
Brothers and sisters, I put my hand over my mouth. Job's silence after God's speech is the right response. There are moments when the correct posture before God is not more words but a hand over the mouth - the recognition that you have been speaking about realities you have not understood, before the One who understands them completely. Receive the silence as gift.
Lord God, we put our hands over our mouths. We have spoken about what we do not understand. You understand all things. We listen. Through Christ our Lord. Amen.
