Nearly half of diocesan priests report at least one symptom of burnout: feeling emotionally drained, worn out, or increasingly negative about their ministry. As the average active priest approaches retirement age, the question is what this number looks like in five years.

Among priests ordained since 2000, nearly half say they're expected to do too many things beyond their calling as priests. That's compared to just 13% of those ordained before 1980.

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 burden is only going to grow.

From our years serving in the Church, we kept seeing the same gap: priests who needed coverage, and brother priests who would have gladly helped — with no simple way to connect.

Clerus closes that gap — connecting priests who need coverage with those who are ready to help, so the rest and renewal they need actually becomes possible. Not to replace the relationships that make coverage work now; but to give them better infrastructure: a secure, private platform built for how Catholic dioceses actually operate — and for the transition ahead.

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.
2
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.
3
Coverage Confirmed
The covering priest receives parking instructions, sacristy notes, and the day-of contact — added directly to his calendar. Custom reminders keep coverage on his radar, no matter how full his schedule gets.

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 matters to him, not requests on the other side of the diocese.

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 feels welcomed and looks forward to returning.

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 hear of the need, check Clerus, and step in to help.
The Day to Recharge
After three weeks without a break, a priest just needs a day to step back. Clerus makes arranging coverage as simple as it should be — so getting rest doesn't become one more thing on the list.
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 Newly Ordained
A priest shepherding three parishes 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.
The Retired Priest
With Clerus, a retired priest 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.
Their Shepherds
When a diocese invests in Clerus, priests don't just get a tool. They get a sign that their shepherds are paying attention — to their health, their wellbeing, and what their days actually look like.

Priest Leadership
Clerus gives priest-leaders a better way to respond: post on behalf of any parish in the deanery or collaborative without the phone calls and endless email back and forth.

After three weeks without a break, a priest just needs a day to step back. Clerus makes arranging coverage as simple as it should be — so getting rest doesn't become one more thing on the list.

Schools and Convents

Clerus
Built and run by Natasha and Michael Hennessy in Grand Rapids, Michigan.



This is why we built Clerus.
We've seen what happens when a priest can't find coverage: the retreat gets postponed, the day off doesn't happen, and the weight keeps building. Clerus addresses one specific friction point: making it easier for priests to get the Mass coverage they need, so they can get the rest and formation they're asking for.
Clerus doesn't replace the relationships that make Mass coverage work now. It gives those relationships a better infrastructure: a secure, private platform built specifically for how Catholic dioceses in the United States actually operate.
