Shared doctrines would include beliefs about one God; the virgin birth; miracles; atonement for sins through the death, burial, and bodily resurrection of Jesus; the Trinity; the need for salvation (through belief in Jesus Christ as the son of God, his death and resurrection, and confession of Christ as Lord); grace; the Kingdom of God; last things (eschatology) (Jesus Christ will return personally and visibly in glory to the earth, the dead will be raised, and Christ will judge everyone in righteousness); and evangelism and missions. Some historically significant Baptist doctrinal documents include the 1689 London Baptist Confession of Faith, 1742 Philadelphia Baptist Confession, the 1833 New Hampshire Baptist Confession of Faith, the Southern Baptist Convention's Baptist Faith and Message, and written church covenants which some individual Baptist churches adopt as a statement of their faith and beliefs.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): When was the Philadelphia Baptist Confession removed?
unanswerable
