A minister is a politician who holds significant public office in a national or regional government, making and implementing decisions on policies in conjunction with the other ministers. Some ministers are more senior than others, and are usually members of the government's cabinet. In some countries the head of government is designated the "prime minister". A government minister with responsibility for religion, such as the Israeli Minister of Religious Services, may be a layperson or cleric but the title should not be confused with the religious position of "Minister (Christianity)" or the activity of Christian ministry.
