The Gospel Halls are a group of independent Christian assemblies throughout the world that fellowship with each other through a set of shared Biblical doctrines and practices.
They typically describe themselves simply as "Christians" gathered to the name of the Lord Jesus rather than adopting a denominational title, which has been a long-standing practice.
One book discussing this phenomenon is an anonymous work called Assembly Life Experiences by "an old disciple", recording the story of a group of Christians who were converted in the 1859 revival in Scotland.
Through reading only their Bibles they concluded that clericalism and denominationalism were unscriptural and subsequently met together to break bread and depend on God for gifting and leadership.
Norman Crawford has documented this story in a chapter of his book Assembly Truth published by Gospel Tract Publications (Glasgow, 1994).
Assemblies meeting in Gospel Halls do not usually print an official statement of faith, but rather, prefer to reference the Bible alone as their authority.
The Easter weekend is also popular for conferences, with notable ones in Belfast, Toronto and Vancouver, as well as some Latin American countries such as Venezuela and Guatemala.
