Which person is a leader of multiple churches within a particular denomination?

In ecclesiastical terms, an individual who leads multiple churches within a particular denomination is commonly referred to as an archbishop. An archbishop typically supervises several bishops and their respective dioceses, overseeing the spiritual and administrative functions of the churches within that jurisdiction. This role includes providing guidance, support, and governance, ensuring that the churches adhere to the doctrines and practices of the denomination.

While a bishop also oversees a group of churches, their scope is usually limited to a specific geographical area and a smaller number of congregations, making the role of the archbishop broader in terms of authority and responsibility. Deacons and pastors, on the other hand, are focused on specific congregations and do not typically have the overarching leadership role that defines the position of an archbishop.
