The Religious Society of Friends originally came into being as a Christian religion. Many Friends today define themselves as Christian. However, Friends do not have a creed. The open, searching, and mystical aspect of Quakerism has led to a diverse membership from a variety of backgrounds and beliefs. A constant theme in Friends' beliefs and history is that daily conduct, social and political action, and religious practice are all expressions of spiritual experience.
Friends value a life style based on simplicity and right use of economic resources.
Many Friends today are actively involved in environmental, or ecological concerns, efforts to promote justice for refugees and First Nations people, and projects designed to promote peace and equality. Many Quakers were imprisoned for their religious beliefs in the early days. Therefore, prison reform continues to be an area of concern for many Quakers. Although Friends are not asked to adhere to any specific code, the Peace Testimony remains central for many Friends. Halifax Friends meeting has a library from which inquirers may borrow materials on Quakers.
