Coordinating Mass coverage should be straightforward.

With Clerus, it is.

Priests post Mass coverage needs in moments — and brother priests across the diocese can see what’s needed and step in.

There’s more to coordinate than there used to be.

The 2025 National Study of Catholic Priests — conducted by The Catholic Project at The Catholic University of America — shows what that looks like for priests across the country.

40% serve two or more parishes

As fewer priests serve in active ministry, those who remain shoulder the weight of multiple communities — and the coordination that comes with it. That coordination grows with every added parish.

Beyond the usual few

Mass coverage has long run on a handful of nearby brothers a pastor knew he could call. As parishes lean on fewer priests, that familiar circle isn’t always enough.

Pulled in more directions

Among priests ordained since 2000, nearly half say they’re expected to do too much beyond their calling — compared to just 13% of those ordained before 1980. Much of that is logistics: the coordination around the ministry, not the ministry itself.

A retreat starts with one question

Priests serving multiple parishes still want the retreats, study, and time away that the priesthood asks for. But for many, the time away begins with a single practical question: who will cover the Masses?

This is why we built Clerus.

In our years serving the Church, we saw a quiet gap: a priest who needed a Mass covered and brother priests who would have gladly stepped in but no simple way for them to connect.

With fewer priests covering more ground, that quiet gap is widening. Clerus closes that gap by connecting priests who need coverage with those in your diocese ready to help.

Mass coverage, simplified by Clerus

1

Post the Coverage Need

A priest needs Mass coverage — for a retreat, a day of rest, or something unexpected. He opens Clerus, fills in the details, and posts the request in seconds.

A Priest Claims It

Brother priests in the diocese — retired, religious, and those with room in their schedule — see the request on Clerus. With one tap, a priest claims the Mass — and the posting priest is notified instantly.

Coverage Confirmed

The covering priest receives parking instructions, liturgy notes, and the day-of contact. Custom reminders keep coverage on his radar, no matter how full his schedule gets.

Every open Mass, in one place

Every open Mass, in one place

The Coverage Board gives priests across the diocese a single view of every open Mass coverage need. They can filter by distance from home, date range, language, or deanery — so a retired priest three miles away sees what’s local to him.

Invite specific priests first

A priest can invite specific brother priests to cover a Mass in a chosen order before a request ever appears on the Coverage Board. If the first priest can’t cover it, Clerus moves to the next — without any follow-up needed.

Already arranged coverage at a deanery meeting? Record it in Clerus so everything stays on the calendar and everyone stays informed, even when the coordination happened in person.

Because every parish is different

Because every parish is different

A pastor sets up his parishes once — arrival instructions, liturgy notes, sacristy layout, and who will be there to help him get set up. Those details go out automatically with every coverage confirmation, so a visiting priest has what he needs the moment he arrives.

A weekly coverage report keeps parish staff informed — who covered what, and when — so nothing falls through the cracks.

When Mass coverage just works.

The Vicar for Clergy

When something unexpected comes up — like a priest in the hospital — it’s no longer an emergency on top of an emergency. Brother priests check Clerus then step in to help.

The Day to Recharge

After weeks without a break, a priest needs a day to breathe. Clerus makes arranging coverage easy so getting rest and renewal doesn’t start to feel out of reach.

The Family Reunion

A priest plans a trip home six months out. He posts his coverage needs on Clerus and it’s confirmed within days — no phone calls, no email chains.

The Retired Monsignor

With Clerus, a retired monsignor can see exactly what’s needed and where — and choose the Masses that fit his pace. Maybe it’s a Sunday in a corner of the diocese he hasn’t been back to in years.

The Planned Absence

A priest facing surgery is looking at weeks away and many Masses to arrange. Instead of managing endless email chains and group texts, he posts the needs on Clerus. With that done, he can focus on healing.

The Newly Ordained

A priest newly assigned to a parish with two missions is still getting to know his brother priests. Clerus connects him to those across the diocese who are ready to help — relationships that would otherwise take years to build.
