We believe that Jesus is the promised Messiah, in whom the prophecies and promises of the Old Testament find their fulfilment. We believe that Jesus is the Son of Man, in that he inherited sin-prone human nature from his mother, and the Son of God by virtue of his miraculous conception by the power of God and although tempted, he committed no sin, and was therefore a perfect representative sacrifice to bring salvation to sinful mankind. We believe that God raised Jesus to immortality, and that he ascended to Heaven, God's dwelling place.

Christadelphians believe that Jesus will return to the earth in person to set up the Kingdom of God in fulfilment of the promises made both in the New and Old Testament, and that Jerusalem will be the capital city of the Kingdom. We further believe that although the Kingdom will be centered upon Israel, Jesus Christ will also reign over all the other nations on the earth.
