A more thorough explanation:

A ministerial office is a type of office that does not involve making decisions or using personal judgment. Instead, the person in this position is responsible for carrying out orders given by a superior or performing duties required by rules, statutes, or regulations.

For example, a clerk in a government agency who processes paperwork according to established procedures is in a ministerial office. They do not have the authority to make decisions or change the rules, but they are responsible for ensuring that the paperwork is handled correctly.

Another example of a ministerial office is a receptionist in a law office. They are responsible for answering phones, scheduling appointments, and greeting clients. They do not have the authority to give legal advice or make decisions about cases, but they play an important role in the functioning of the office.
