According to the Eastern Orthodox Church and Roman Catholic Church, completed revelation is the doctrine that God has fulfilled and completed divine revelation in Jesus, and there will be no new divine revelation until the Second Coming.
The Roman Catholic Church believes Jesus Christ is the "fullness and mediator of all Revelations",[1] and that no new divine revelation will come until the Second Coming.[2] It also believes that God gradually leads the church into a deeper understanding of divine revelation, such as by private revelations,[2] which do not fulfill, complete, substitute or supersede divine revelation but help one live by divine revelation.[3] The church does not obligate the faithful to believe in, follow, or publish private revelations, whether they're approved or otherwise.[3]
