Hello FireDragon,
Thank you for the French translation, but I think it would be inappropriate for me to express myself in French. For my part, I prefer to continue in English.
I understand your approach, but it seems to allow everyone to be corrupted in terms of righteousness in your interpretation, from the one who originated it (the steward) to his master who endorses it, including all the debtors.
To understand some of Jesus parables, you have to look at them "from below" , from the point of view of peasants. This isn't about being fair in the sense of liberal Enlightenment values. This is about being wise, not about being fair in the usual sense.
In some respects, your interpretation makes sense.
But if we look at the parable from the beginning, we may wonder about the significance of the first two verses. Why this staging? Why these threats to dismiss the manager if you are right? What is the point of the rest of the parable? From the first verse, the master could have chosen to check the steward's accounts without threatening to remove him from his position, since he ends up praising him without further threats for reasons similar to those for which he is accused: squandering his property.
If the master is a good master, either he would not have reacted so harshly to his steward's denunciation (Luke 16:2), or he would have reacted in the same spirit as this verse, namely, not to squander his property. Otherwise, I think we could conclude that the master has a split personality.
If this seems scandalous to you, just go read some of the Old Testament stories. YHWH is a God of covenant promises, not cosmic order, unlike many pagan gods of the time (Egypt), and is frequently involved in subverting expectations of power and birthright. Jacob takes Esau's inheritance through shrewdness, not through fairness, and yet God honors that nonetheless.
In my interpretation, God does not honor Jacob's cunning shrewdness.
He is simply keeping his promise.
Between two men who were claiming an inheritance, Jesus too seems unconcerned (Luke 12:13-14).
I am not sure that keeping his promise means for God to honor Jacob's shrewdness.
