Pastoral Support

One of the privileges of Mater Dei Campus Ministry is to support our students in all aspects of their lives but especially during these challenging times we want to assure you of this gift through pastoral ministry.

At Mater Dei the spiritual well-being of our students is of primary importance and integral to our mission as we daily strive to develop the whole person. Pastoral care provides a positive, nurturing presence for those who need accompaniment on their life journey through compassionate listening and prayer. This ministry offers ongoing support to all those students and their families who have faced challenges in their lives, and is especially sensitive to student’s illness or the loss of a loved one.

It is truly our honor to provide this ministry as we hold each family in our daily prayers.
