Each Advent, Gesu "plants" a Christmas tree near the east altars and invites parishioners to trim this Advent Mitten Tree. The first Sunday of Advent marks the start of our annual-sharing project for the home with gifts of warmth: new mittens, caps, scarves and gloves for homeless children and adults of several shelters for Milwaukee’s homeless and victims of domestic violence. Since 2002, we have also planted a Haiti Children’s Tree, which parishioners decorate with bars of soap, toothpaste and brushes, underwear, shoes and socks, and hair clips and ribbons for the children of St. Jude, our twin parish in Haiti.

Since 1997, Gesu has ministered to Milwaukee area homeless women and children, in order to alleviate the suffering of being homeless. Gesu's Cathedral Center Ministers are volunteers, coordinated by a parishioner, who are scheduled to serve in teams, 6:30-9:00 p.m., for two weeks every other month. Shelter ministers provide hospitality, conversation and compassion.
 

The social ministries are active year-round and open to all parishioners to join in making the social mission of the church the essential and central mission of the parish.  Examples of ministries include: parish twinning with St Jude's parish in Haiti, ongoing social justice eduation programs, and fair trade coffee sales.

Gesu Social Concerns Committee oversees a number of programs to the homeless including a regular Saturday meal program, Sunday breakfast bags. Gesu parishioners also partner with downtown congregations offering shelter and day programs to the homeless individuals and families and Gesu parishioners were instrumental in the establishment of a Milwaukee Housing Trust Fund

Parishioners share non-perishable food items and disposable diapers which are collected each Sunday in baskets in the Upper Church. These donated items are brought to Frieden's Community Ministries food pantry about every three weeks.

Midnight Run is a volunteer service program which began in 1988. It focuses on the particular needs of the hungry and homeless people living in the community around Marquette. This program is organized by a coordinating team of Marquette students under the supervision of Campus Ministry. Volunteers serve meals and work in area meal programs and shelters. Service in Midnight Run is meant to challenge students to integrate their experiences with their faith. Midnight Run's philosophy is rooted in the gospel, with Matthew chapter 25 serving as its hallmark. Midnight Run is based on the fundamental belief in the dignity and worth of all persons and strives to cultivate a sense of responsibility for caring for all members of our community.

For over 20 years, the campus ministry program Midnight Run has utilized voluntary direct service (primarily nutrition and meal outreach) as its primary tool to “build relationships, and walk with those who are hungry, homeless, or suffer the consequences of society's unjust structures, honoring the dignity and worth of all.” Through reflection on service Midnight Run seeks to create men and women of service and develop agents of positive social change.

MICAH organizes/advocates around issues such as neighborhood drug trafficking, urban schools, drug punishment and rehabilitation, affordable housing, and urban sprawl. This church-based organization is grounded in the principles of empowerment through the Gospel, education, advocacy and action. The Gesu MICAH Core Team leads parish actions in this interfaith, multi-racial organization to empower people to achieve structural change for justice and peace in the innercity.

On the 1st, 2nd and 3rd Saturdays, the Gesu/Midnight Run Soup and Sandwich Meals are offered in the Fr. Herian Parish Hall to the hungry, the homeless, the elderly and the needy in the parish and the neighborhood.

Service is a significant part of most students’ Marquette experience through New Student Orientation, in student organizations, as part of residence floor activities, in classes, and as part of leadership development programs and athletic teams' activities. The Office of Student Development at Marquette University coordinates community service programs like Best Buddies, Habitat for Humanity, literacy training, jail visitations and Hunger Clean Up.  The OSD invites Marquette student to strive to “Be the Difference!”

Breakfast Bags for the hungry are provided at the Parish Center entrance each Sunday Morning from 8:30 a.m. until gone.
