The Twenty-ninth Sunday in Ordinary Time is marked by significant readings from Exodus, Psalm, 2 Timothy, and Luke.
Luke tells us that the parable is about praying always without becoming weary (Luke 18:1), a lesson for the disciples after Jesus discussed the coming of the kingdom.
They ought "to pray always without becoming weary"
The kingdom is both already and not yet, requiring the disciple to pray without losing heart, exemplified by the "importunate" widow.
The parable's characters, including the stonehearted judge and the persistent widow, are drawn to underline the moral, possibly with a humorous intent.
