Although the Reformation was a religious movement, it also had a strong impact on all other aspects of life: marriage and family, education, the humanities and sciences, the political and social order, the economy, and the arts. Protestant churches reject the idea of a celibate priesthood and thus allow their clergy to marry. Many of their families contributed to the development of intellectual elites in their countries. Since about 1950, women have entered the ministry, and some have assumed leading positions (e.g. bishops), in most Protestant churches.
