Jesus used a woman in the "Parable of the Lost Coin" as a metaphor for God.

A female image of God would incite anger from the Pharisees.  

Here's the parable - Luke 15:10 - "Or what woman, if she has ten silver coins and loses one coin, does not light a lamp and sweep the house and search carefully until she finds it?" 

God was never depicted as female in Jewish tradition. There is no known precedent in the Hebrew Scriptures or contemporary Jewish literature for portraying God as a woman.  

To compare the Most High to a poor Galilean housewife searching for a coin would have struck many as irreverent at best, blasphemous at worst. Portraying God as a woman sweeping her house subverted both their theological imagery and their social hierarchy. 

Far from being a casual detail, it was a deliberate rhetorical move by Jesus to confront religious pride and reveal that God’s joy over repentant sinners transcends human categories of gender, status, and honor.
