The Office of the Vicar for Priests exists in order to promote the personal and ministerial well-being of the priests of the Diocese of Phoenix. It also exists in order to promote the fraternal bond that unites the priests in one presbyterate of Diocesan and Religious Order priests, active and retired priests. This well-being is promoted through the Vicar of Priests who works with three committees established within the Diocese to address the issues and concerns of priests: the Priestly Life and Ministry Committee, the Priests' Placement Board, and the Priests' Ongoing Education/Formation Committee.

The activities of the Vicar for Priests include but are not limited to the following:

• Visitation of priests in the parishes, their work place, the hospital, their home, etc. in order to offer personal support.
• Sacramental ministry on weekends in parishes when the local priest is away on vacation, retreat, workshop, sickness or other reasons.
• Assistance in finding priests for weekend help in the parishes.
• Programs for first time pastors and recently ordained, retreats and days of recollection for priests, priests' continuing education days and the priests' convocation.
• Social events and dinners as well as various kinds of gatherings for the priests.
• The monthly UPDATE newsletter for priests.
• Financial and moral assistance to priests in special circumstances.
• Staff support for the Priests' Placement board in the work of recommending to the Bishop assignments of priests to parishes and other ministries in the Diocese.
• Assistance to priests in planning sabbaticals and ongoing educational experiences.
• Assistance in the process of welcoming priests from outside the Diocese of Phoenix who wish to live and work here.
