For whatever it’s worth, one of the books on Pope Benedict XVI, I believe it’s “Servant of the Truth”, listed his salary, when he served as Prefect for the Congregation for the Doctrine of the Fatih, at the equivalent of $1,200 a month.
Closer to home, our pastors make $1,400 a month while the parochial vicars make slightly less. So, if a priest were to serve as the director of divine worship for his diocese, that might be in addition to his pastoral duties as either rector, pastor or parochial vicar of the individual church to which he is assigned. The diocese would then configure the amount on the basis of his responsibility to the particular offices he held.
Now, if the director were from a religious order, there are some orders who would require that the salary be given to the community, as communal property, meaning that the nun or brother would not have the money for his or her own personal use. It goes to the house, so to speak. The brothers at our local priory share everything in common, so when one of them celebrates Mass, the stipend is made out to the priory rather than to the individual priest. Ditto for those who also teach at our local community college and university.
The lay diocesan directors make anywhere from $36,000 to $40,000 depending on education and experience. I couldn’t tell you how much our bishop makes because that’s not public knowledge. What I do think is that the diocese pays for his house and other incidentals.
