"Is there anyone still left of the house of Saul to whom I can show kindness for Jonathan's sake?" (2 Samuel 9:1)
David asks: Is there anyone still left of the house of Saul to whom I can show kindness for Jonathan's sake? He is told about Mephibosheth, Jonathan's son, who is crippled in both feet. David sends for him. Mephibosheth comes and falls on his face: what is your servant, that you should notice a dead dog like me? David says: do not be afraid; I will show you kindness for the sake of your father Jonathan. I will restore to you all the land that belonged to your grandfather Saul, and you will always eat at my table. Mephibosheth is settled in Jerusalem and eats at the king's table like one of the king's sons.
Mephibosheth is one of the most powerful figures in the Old Testament as a type of the sinner's reception by God. He is crippled, living in hiding, from the house of a defeated king, calling himself a dead dog. David restores his inheritance, seats him at the royal table, and treats him as a son, for the sake of the covenant made with his father. The Catechism identifies this scene as a figure of the Eucharist: the broken one, brought from Lo-debar (the place of no pasture), seated at the king's table where he always eats, as one of the king's own sons (CCC 1384).
Brothers and sisters, Mephibosheth called himself a dead dog and David called him a son of the king. The identity we have from our past failure, our crippling, our exile, is not the identity David's greater Son gives us. He says: come to my table. Eat here. You are mine. Stop calling yourself a dead dog.
Lord Jesus, for the sake of your covenant with our Father, bring us from Lo-debar and seat us at your table. Restore what was lost. Call us sons and daughters. We come, crippled and afraid, and you feed us at the royal table. Through Christ our Lord. Amen.
