The English Roman Catholic scholar Cardinal John Henry Newman argued that the essence of the doctrine is locatable in ancient tradition, and that the core consistency of such beliefs are evidence that Christianity was "originally given to us from heaven". Roman Catholics consider the teaching on purgatory to be part of the faith derived from the revelation of Jesus Christ that was preached by the apostles. The descriptionsand doctrine regarding purgatory then developed over the centuries.
