Christadelphians openly deny almost every essential doctrine of historic Christianity, including the Trinity, the deity of Christ, salvation by grace through faith, and the substitutionary atonement of Christ. They also deny the immortality of the soul and the reality of eternal conscious punishment for the wicked. Depite their rejection of orthodox Christian doctrines, they claim to be the one true church, the remnant of faithful disciples left over from a partial apostasy: ''The Bible predicted that the time would come when the original faith of the Gospel would be obscured by error, and this came to pass in the fourth century after Christ...there always have been those 'few' (Luke 12:32) from the days of the Apostles to the present ages, who have kept the light of truth shining... Each little group, down through the ages, like links in a chain, connect the testimony of the Apostles with the teaching of Christadelphians today'' (Introducing the Christadelphians, pp. 6-7)
