In the United Methodist Church, the preaching of the deacon is an underdeveloped voice that should be included among all the other preaching voices in the church. The preaching voice of the deacon is grounded in their call to compassion, justice, reconciliation, and restoration, and is informed by biblical and historical contexts that affirm and confirm the value and necessity of such preaching. Naming and claiming the voice of the deacon as preacher requires deacons to understand themselves, their call to ministry, and the relevance and importance of their voice that calls attention to the need for justice in action as valid and necessary in our world today. The voice of the United Methodist deacon as preacher is a necessary voice in the local church and beyond for the advancement of social justice. This project thesis rests on the belief that for the United Methodist deacon, claiming their voice as preacher helps them more fully fulfill their call to ministry and live into their baptismal and ordination vows.
