Until around the 1900s, parables were generally interpreted allegorically.

Today it's a big no, no.  Perhaps some day it will be preferred again?

Anyway, I'm not familiar with the rules of allegorical interpretation, and strangely, I have need to know how the parable of the persistent window (Luke 18) has been interpreted through the ages.

Thanks for any help,

Men ought always to pray—Therefore the plain meaning and moral of the parable are evident; viz. that as afflictions and desolations were coming on the land, and they should have need of much patience and continual fortitude, and the constant influence and protection of the Almighty, therefore they should be instant in prayer. It states, farther, that men should never cease praying for that the necessity of which God has given them to feel, till they receive a full answer to their prayers. No other meaning need be searched for in this parable: St. Luke, who perfectly knew his Master's meaning, has explained it as above.

—Adam Clarke's Commentary

A.Clarke wrote it in the mid of the 19th century.

I think that's that.What else could there be?

But if someone knows some other way to interprete the parable, please, share your thoughts!

Thank you!
