With a due respect, I wouldn’t say this in public. You may put your diocese on the spot. You wouldn’t want to do this.
If the deacons and their wives shared this information it’s because you’re a friend. Information about income and salaries is usually very confidential.
As to permanent deacons receiving a salary, that is not the norm in the Church. Only those who hold a post receive a salary for that post.
Even priests and religious receive a salary for the post they hold, not for their ministry.
We have seven friars and two deacons. Our deacons are not on the payroll, because they are not parish staff, even though they are clergy. The superior of the house does not receive a salary, because he’s not parish staff, even though he’s the pastor’s superior. The pastor, the associates and two friars who are not priests, but work for the parish receive salaries that go to their community.
The two deacons and the two friars who are not on the staff receive no funds from the parish, even though they do ministry in the parish. Those are the rules of the US Bishop’s Conference.
If your bishop pays the deacons, that’s a diocesan policy, not a universal policy.
