4.7 Christadelphian’s defective eschatology. http://www.christianlibrary.org.au/cel/documents/cults/04.html
Another common feature of many of these cults is a defective view of the doctrine of the Second Coming of Christ. Christadelphians have a particularly interest in future events. Like the Jehovah’s Witnesses they major on prophecy. Much of their advertising deals with this subject. Despite Jesus’ declaration in Matthew 24:36, that no one knows the day and hour of Christ’s return except the Father, they persist in trying to work out dates for the Second Coming of Christ. They have repeatedly predicted the outbreak of Armageddon. Like the Jehovah’s Witnesses, they have often come unstuck with their prophesies, and so have been forced to revise their theories at a later date. In 1866 the Christadelphians published a pamphlet entitled, Ambassador of the Coming Age, which said:
“It is pretty certain that Jesus will return within the lifetime of the present generation.”18
Jesus did not come as they had predicted. They failed to understand what Jesus said to His disciples: “It is not for you to know times or seasons which the Father has fixed by His own authority.” (Acts 1:7)
Christadelphians have a mistaken view of the kingdom of Christ. They see it, not so much as having already come and being manifested in the rule of God in men’s hearts, but rather as a visible kingdom that will take place after Christ’s second coming. In their understanding Christ’ is not now King and will not be until after His Second Coming. In their teaching only Christadelphians will have reached the required standard to enter His kingdom when it comes. Only they will be resurrected and will gain immortality. Christadelphians anticipate the day when they will rule with Christ in His kingdom. They maintain that His Kingdom will be worldwide, with its administration centred in Palestine. They believe that only Christadelphians and Jews have any hope of the resurrection.
This view of the kingdom is entirely contrary to the teaching of the Holy Scriptures. For the Bible teaches that Christ’s kingdom came in power on the day of Pentecost (Matt. 16:28). A cursory reading of the New Testament clearly reveals that Christ’s kingdom has already come.
