1. Freedom or liberality of opinion, particularly in theology.
2. Indifference to religion.

Latitudinarism was initially a pejorative term applied to a group of 17th-century English theologians who believed in conforming to official Church of England practices; but who felt that matters of doctrine, liturgical practices, and ecclesiastical organization were of relatively little importance.

The term has taken on a more general meaning, indicating a personal philosophy which includes being widely tolerant of other views, particularly; but not necessarily, on religious matters.
