About Us

The Christadelphians are a world-wide religious community who aim to return to the faith and character of the early Christian church as it was nearly 2000 years ago.

We have been active in the Castle Hill area for more than 30 years.

The name “Christadelphian” means “brothers and sisters in Christ”. Jesus Christ has brought us together into a special relationship as spiritual brothers and sisters who are children of God.

Our Faith

We base our faith entirely on the Bible. We believe that the Bible contains God’s message to men and women. There is no other book like it.

Our priority is to get back to the real meaning of the Bible. In the Bible, God has told us about His great purpose with mankind and the earth. God has promised us a wonderful future which fills us with hope and gives meaning to our lives.

Our Community

We are located in many countries throughout the world with large groups of Christadelphians in the United Kingdom and Europe, Australia and New Zealand, North America, South East Asia and Africa.

Like the early Christians, we meet in homes, rented rooms and, in some case, our own halls.
Acts 1:13-14; 2:46-47; 18:7; 19:9; 28:30

We are a lay community patterned after first century Christianity. Each congregation is called an “ecclesia” (the New Testament Greek word for church).

We have no paid clergy or church hierarchy. Members of each congregation are addressed as “brother” or “sister”, and all are involved organising our activities. All members contribute their time and energy voluntarily in service to God. A strong common belief binds our brotherhood together.
Rom 12:4-8; 1 Cor 12:4-27; Gal 3:28

Brief History

Many believers since the apostles have held the same faith as the Christadelphians. There have been countless independent communities around the world who have eagerly studied the Bible and accepted its simple teachings.

The Christadelphians trace their history to the mid-1800s. In 1830, an English Physician named John Thomas sailed to America. On the voyage, the ship met some unexpected bad weather and nearly sank. For the first time, Dr Thomas faced the reality of his own mortality and was dismayed to discover that he was not sure what lay beyond death. In the midst of the storm he vowed that, should he survive, he would not rest until he had found a satisfactory answer.

He did survive and kept his vow, beginning a life-long search for the truth. It soon became evident that many of the doctrines that were popularly taught and believed were inconsistent with the Bible. Dissatisfied, Dr Thomas devoted himself to a careful independent study of the Scriptures. He made no claim to any vision or personal revelation.

The work of Dr Thomas attracted the support of others in America and Britain who were convinced of the truth of his conclusions. Together they formed the Christadelphian community. Since then, Christadelphian communities have been established in many countries all over the world.

Summary of Beliefs

The Bible

We believe that the Bible is God’s only revealed message to mankind, given to bring responsive individuals to the obedience of faith. The Bible is our only authority and we teach that it should be read prayerfully and with care at every opportunity.
Rom 16:26; Acts 17:11; 2 Tim 3:16-17; 2 Pet 1:20-21


There is only one eternal, immortal God. Jesus Christ is his only begotten son and the Holy Spirit is his power.
Isa 45:5-7; 1 Tim 1:17; Luke 1:35; Acts 1:8; 1 Cor 8:6


Man is mortal and a sinner before God. His whole being is prone to sin and the punishment for sin is death – the end of life.
Job 4:17; Rom 3:23; Jer 17:9; Mark 7:21-23; James 1:13-15; Rom 6:23; Eccl 9:5-10; Psa 146:4


In his love, God sent his son, the man Jesus into the world to save men from their sins. Those who believe in him will not perish, but have everlasting life.
Luke 1:35; Matt 1:20-21; 3:17; John 3:16


The only hope of life after death is the resurrection of the body and everlasting life in God’s kingdom on the earth.
Psa 49:12-20; 1 Cor 15:12-50; Rom 8:22-39; Acts 24:15; John 11:25-26; Rev 5:10; 20:4

Sacrifice of Christ

Jesus was sinless. He died to show God’s righteousness and to redeem those who receive this sacrifice by faith. God raised him from the dead, gave him immortality, granted him all authority in heaven and on earth, and set him as the mediator between God and man.
Eph 1:19-23; 1 Tim 2:5-6; Heb 4:14-16; Rom 3:21-26

Return Of Jesus

Jesus will return to the earth soon. Then he will raise many from the dead, judge them along with those still living, and give his faithful followers everlasting life in the kingdom of God.
Acts 1:11; Rev 22:12; Luke 21:20-32; John 5:28-29; Dan 12:2; 2 Tim 4:1; Matt 25:31-34

Kingdom of God

The kingdom of God will be established on earth. Jesus will be king in Jerusalem, his dominion worldwide and his government will bring eternal righteousness and peace.
Dan 2:44; 7:27; Acts 3:21; Jer 3:17; Isa 2:2-4; Psa 72; Dan 7:14; Isa 9:6-9; 11:1-9; 61:1-11

The Promises

The Gospel is inseparable from the promises which God made to Abraham and David in Old Testament times. These promises find their fulfilment in Jesus Christ.
Gal 3:6-9,16,26-29; Gen 13:14-17; 22:15-18; 2 Sam 7:12-16; Luke 1:31-33

The Way of Salvation

The way to enter the kingdom of God is by faith. This involves belief in the Bible and obedience to its requirements that men and women confess their sins, repent, be baptised and follow Jesus faithfully.
Heb 11:6; 1 Thess 2:13; 2 Tim 3:15; Acts 2:37-38; 4:12; Mark 16:16; John 3:3-5; Matt 16:24-27

Important Differences

Often we are asked, “How are you different from other Christian Groups”?

Apart from our distinctive organisation (with no clergy or hierarchy), some of our doctrines are quite different from most churches.

For example, we reject the doctrine of the “Trinity”. This doctrine developed 300 years after Jesus died as a result of disputes within the orthodox church. The Bible teaches that Jesus is the Son of God but nowhere does it speak of him “pre-existing” in heaven as “God the Son”.

We also reject the idea of an “immortal soul” that goes to heaven at death. The Bible teaches that the only hope for eternal life is through a resurrection when Jesus returns.
Another difference is that we believe that baptism is essential and for adults only. We believe that sprinkling of babies is not baptism.

We also believe that the Bible uses the “devil” as a symbol of sinful human nature, and so we reject the doctrine of a supernatural tempter.
