I strongly recommend you read this article by Father Dwight Longenecker about St. Jerome:
"From his cave he continued his intellectual battles: he argued with Heldivius and Jovinian’s ideas that the Blessed Virgin had other children by Joseph. He combatted a monk Vigilantius who was down on the veneration of relics and celibacy and even crossed swords with Augustine.
Maybe it is the monk in me, the recluse, the bookish hermit in me that would also like to retire to a cave somewhere, but Jerome reminds us that “the church of nice” isn’t the only way. Jerome rightly warns us against worldliness, sentimentality, intellectual shallowness and cowardice. He reminds us to fight the good fight with all our might, and if he descended into sarcasm and satire, he was also always aware of his own weakness, temptation and soiled humanity.
The fact that Jerome is plonked down right there between the angels, Therese and Francis reminds us that the army of saints needs little flowers and holy friars who preach to birdies, but it also needs saints with True Grit.
We need some Rooster Cogburn Catholics as well as the sweet little girls, the angels and the beautiful foolish dreamers."
