All churches have ministries, but not all ministries are churches. A ministry is a specific form of outreach that glorifies God and cares for others and is typically run by volunteers from within a church. A few examples of ministries include prayer ministry, men/women’s ministry, kids ministry, and more.
On the other hand, a church is the hub where multiple ministries are supported spiritually and financially. Ministries are just one part that makes up a church. Churches also include worship gatherings, non-worship activities, and official leadership structures.
