Members of St. Peter's reach out to the community in a variety of ways. The annual Oktoberfest raises funds for the Victoria Affiliate of Habitat for Humanity, camping ministry, and other community organizations. Gifts of food and clothing are provided to Goliad County Outreach, and birthday parties are celebrated for nursing home residents. On a Sunday before Christmas Day, Christmas carols are shared with residents of nursing homes and area residents.
A 2-mile section of FM 1961 has been adopted as part of Texas Highway Trash Pickup.
Camp work weekends are held each spring at one of the synod's camps, and a variety of community groups make use of the church's parish hall and picnic area.
St. Peter's participates in the ministry of the whole church through mission support gifts. These gifts - for the work of the church in our local area and throughout the world - support the development of new congregations in the United States and the Caribbean, the ministry of missionaries serving with partner churches throughout the world, educational ministries at colleges and seminaries, campus ministry at both state and private universities, and the development of resources for worship, youth ministry, and outreach.
Additional designated gifts through St. Peter's help support the work of missionaries in Madagascar, the World Hunger Appeal, and Lutheran World Relief.
Funds are also available to assist area residents in need, and several members currently or in the past have served on synodical and churchwide boards and committees.

Twenty-four members and friends of St. Peter's participated in the 43rd-annual camp work weekend, held May 20-22 at Lutheran Camp Chrysalis near Kerrville. The work weekend included the construction of enclosures surrounding serveral propane tanks and electrical transformers. Chrysalis is one of two camps operated by Cross Trails Ministry.
