Religious liberalism that were identified to religious movement

Religious liberalism is a conception of religion (or of a particular religion) which emphasizes personal and group liberty and rationality. It is an attitude towards one's own religion (as opposed to criticism of religion from a secular position, and as opposed to criticism of a religion other than one's own) which contrasts with a traditionalist or orthodox approach, and it is directly opposed by trends of religious fundamentalism. It is related to religious liberty, which is the tolerance of different religious beliefs and practices, but not all promoters of religious liberty are in favor of religious liberalism, and vice versa
