St. Jerome was a straight shooter when it came to speaking the truth, not afraid of what anyone thought about him. Most often his words drew the ire of his fellow priests.
This can be seen clearly in a letter to the priest Nepotian, who abandoned the military for the clerical calling. St. Jerome wrote extensively about the duties of a priest and had harsh words for those who sought fame and fortune.
St. Jerome had a preference for the poor, not only in ministering to them, but also for the simplicity of ministers. He believed a priest should be humble and not seek after wealth.
When it comes to accepting large donations for personal needs, St. Jerome urges priests to refuse them.
Above all, St. Jerome tried to express in his letter that a priest should practice what he preaches, being a poor man among the poor, serving them and seeking no earthly fame.
