"She is more righteous than I, since I would not give her to my son Shelah." (Genesis 38:26)
The story of Judah and Tamar interrupts the Joseph narrative, inserted here for theological reasons that become clear at the end. Judah separates from his brothers, marries a Canaanite woman, and has three sons. The first, Er, marries Tamar but is wicked and the LORD puts him to death. Judah tells his second son Onan to fulfil the duty of a brother-in-law and raise up offspring for his brother. Onan, knowing the children would not be counted as his, spills his seed on the ground whenever he lies with Tamar. The LORD puts him to death also. Judah tells Tamar to live as a widow in her father's house until his third son Shelah grows up, but he does not intend to give Shelah to her, fearing he will die too.
Tamar realises Shelah has grown up and she will not be given to him. When Judah goes to shear his sheep, she disguises herself as a prostitute and sits at the roadside. Judah sleeps with her, giving her his seal and staff and cord as pledge of payment. She conceives. When her pregnancy is discovered Judah orders her burned. She produces the seal and staff: I am pregnant by the man who owns these. Judah acknowledges them and says: She is more righteous than I, since I would not give her to my son Shelah. She bears twins: Perez, from whose line David and ultimately Christ will descend. Tamar, a Canaanite woman who claimed her covenant rights by unconventional means, is listed in Matthew's genealogy of Jesus alongside Ruth and Rahab. The Catechism notes that God works through the full range of human experience, including its moral complexity, to accomplish his purposes (CCC 312).
Brothers and sisters, she is more righteous than I. The moment Judah acknowledged Tamar's righteousness and his own failure was the moment of moral clarity that allowed the story to move forward. The willingness to say she was right and I was wrong, spoken aloud, is one of the hardest sentences in human speech and one of the most necessary. Who in your life deserves that sentence from you?
Lord God, you placed Tamar in the genealogy of your Son, the Canaanite woman who claimed her rights against the one who withheld them. Give us Judah's courage to acknowledge when we have been less righteous than the one we judged. Through Christ our Lord. Amen.
