The Christadelphians ("Brothers and Sisters in Christ") are a body of
Bible believing people, who aim to live by faith in Jesus Christ, finding
their instruction in a wholly inspired Bible. Jesus Christ will one day
return to the Earth to establish the Kingdom of God and grant eternal
life to his people - those who have tried to follow him and God.

The fundamental Christadelphian beliefs are:

The Bible is God's word and the only message from Him. It is
without error, except for copying and translation errors.
(2 Timothy 3:16, Hebrews 1:1)

There is only one God - the Father. The Holy Spirit is God's
power.
(John 17:3, Luke 1:35, Deuteronomy 6:4)

Jesus is the Son of God, a human being, born by his mother
Mary.
(Luke 1:30-31, John 3:18)

Man is mortal, having no existence when dead.
(Psalm 6:5, Isaiah 38:18, Acts 2:29-34)

By living a sinless life, ending with his sacrificial death by
crucifixion, Jesus has opened the way of salvation from death.
(Hebrews 4:15, 1 Corinthians 5:7, 1 Corinthians 15: 20-23, Galatians
3:27-29)

Belief and baptism are essential steps to salvation.
( Mark 16:16)

God raised Jesus from death. Jesus is currently in Heaven, on
God's right hand. He will one day return.
(Acts 10:40, Romans 8:34, Acts 1:11)

When Jesus returns, he will raise his "sleeping" followers from
death and grant immortality to the faithful who have tried to live
by God's precepts.
(1 Corinthians 15:20-22)

His followers will help him to rule, bringing justice, righteousness
and peace to the whole world - the Kingdom of God.
