Grace Redeemer Church is a Presbyterian church whose spiritual leadership rests with the Session—a body comprised of Teaching Elders (i.e. pastors and associate pastors) and Ruling Elders. The Elders are called to shepherd the flock; to teach the Scriptures to the congregation; to guard the church from false teaching; and to demonstrate Christ-like character.
The Diaconate is a ministry of mercy reaching out to people who are needing help amid life’s struggles, both within Grace Redeemer Church and in the surrounding community. The goal is to show others how God’s provision always imparts opportunities for change.
Deacons and deaconesses serve sacrificially and humbly, embracing the faith and modeling Christ as servant-leader. Here are a few ways they function:
- Organize financial assistance for basic living expenses (rent, food, medical bills, etc.).*
- Provide subsidies for counseling services.
- Offer prayer, spiritual guidance, and accountability.
- Schedule meal deliveries for congregants with special circumstances.
- Assist with Biblical stewardship and budgeting guidance.
- Connect people with county and statewide support services.
- Assist GRC staff in caring for the church building, and running Sunday service operations.
- Interact with select outside ministries and coordinate support for them.
* Because funding is limited, we direct financial support to the neediest. The Diaconate serves those in crisis and is funded entirely by GRC congregant donations. Therefore, they are accountable to the congregation to be wise stewards of the resources God has given through His people.
Current members of the Diaconate include: John Cordova, Shelley Hahn, Gloria Huang, Gabe Naranjo, Werner Tretner, and Jeffrey Wan.
