"May the Lord of heaven bring you joy in place of your sorrow. Be of good cheer, my daughter." (Tobit 7:17)
Tobias and Raphael arrive at Raguel's house. Raguel is struck by Tobias's resemblance to Tobit and learns they are indeed kinsmen. When he hears Tobit is blind he weeps. Tobias asks for Sarah in marriage. Raguel is honest: I am afraid that you might die like the others. But Tobias presses him, and Raguel agrees: the marriage is in God's hands. He calls for Sarah, takes her hand, and gives her to Tobias. He draws up the marriage contract. Sarah's mother Edna weeps; she wipes her daughter's tears and says: may the Lord of heaven bring you joy in place of your sorrow. Be of good cheer, my daughter. The Lord of heaven grant you joy for this your sorrow. Be of good cheer, my daughter.
The Catechism identifies the drawing up of the marriage contract in Tobit as the earliest explicit reference to a written marriage covenant in Scripture: the covenant of marriage is a legal reality that the whole community recognises and the family solemnises (CCC 1627).
Brothers and sisters, Edna wept with her daughter and then blessed her: may the Lord bring you joy in place of your sorrow. The mother who weeps with the daughter about to take a risk and then prays the blessing over her is the mother who combines honest love with faithful hope. Weep with those you love. Then pray the blessing. Both are necessary.
Lord God, may you bring joy in place of sorrow to every bride and groom who comes to you in fear and hope. Be of good cheer. The Lord of heaven is with you. Through Christ our Lord. Amen.
