Introduction and History
The founder of the Christadelphians (“brethren of Christ”) was John Thomas, a physician turned Bible teacher, born in London on April 12, 1805. In 1832, during a brush with death in a shipwreck, he resolved to look into the truth about the afterlife and vowed to dedicate his life to religion if he was spared. His first experience with “Christianity” was with the often unbiblical Campbellite movement (today known as the “Church of Christ,” “Christian Church” or the “Disciples of Christ”). In 1833 Dr. Thomas had met Alexander Campbell and was influenced by his teachings. Eventually he left the Campbellites and continued studies on his own. In 1847, he claimed that he had arrived at “the truth of the gospel.”  His best known works are Elpis Israel (“Israel’s Hope,” 1849) and Eureka (1862), a 2,000 page study of the book of Revelation. Both are published and used by Christadelphians today. The Christadelphian is the principal periodical of the Church. It was originally titled The Ambassador of the Coming Age and begun by Robert Roberts, one of Thomas’ earliest converts. Roberts became the leader of the Christadelphians after Thomas died in 1871.
Like Joseph Smith in Mormonism, John Thomas seems to have derived many of his ideas from the theological climate of the day. Although he believed that he was reviving “original Christianity,” some of his teachings paralleled the early Unitarians, while other teachings were drawn from diverse sources. In The Protesters, Christadelphian writer Alan Eyre expresses his surprise up on learning of Dr. Thomas’ many borrowings: “The writer, once naively and unquestioningly accepted the popular view that Dr. John Thomas ‘discovered,’ as if from a void, the totality of Bible truth as believe by Christadelphians, was amazed to discover source after source which showed that this was at least a serious misrepresentation.” 
The Christadelphians meet in “Ecclesias” or local congregations. The first were established by Thomas in 1838 in Illinois and Virginia. The church was officially incorporated in 1864, being registered at the county court house in Oregon, Illinois. Today the church is scattered around the world and is principally found in the United States, Europe and Africa.
Many modern religious cults claim not only that they are Christian but also that they represent the restoration of original Christianity. Along with Mormons, Jehovah’s Witnesses and Christian Scientists, this is also true for the Christadelphians. For example, Christadelphian author Alan Haywood quotes skeptical philosopher Bertrand Russell, author of Why I Am Not a Christian, in alleged support of Christadelphian apostolic Christian claims: “The best representatives of the primitive [Christian] tradition in our time are the Christadelphians.” Other Christadelphians declare, “In short we are people of the Bible.” “First-century Christianity was thoroughly Bible based, and so we try to make our faith like that, too.” “The Bible is our only authority, and we teach that it should be read prayerfully and with care at every opportunity.”
The truth is that Christadelphians oppose historic orthodoxy and view biblical Christianity as a pagan religion. This is why it is declared to be “paganized theology,” and even “meaningless.” Christadelphians are told that the true church of Jesus “and modern Christianity are as different as night and day.” “The creeds of Christendom are based on false doctrines, compounded of a little Bible teaching, but mostly composed of fables, based upon pagan mythology.” 
In addition, Christadelphians see little difference between Protestants and Catholics, almost as if the Reformation had never occurred. In essence, Christadelphianism condemns Protestantism because it has many of the same doctrines of Rome:
The principal doctrines of the churches of Christendom are these same Romish doctrines. They are as follows: 1. The Trinity, 2. The pre-existence of Christ, 3. Christ the Creator, 4. The immortality of the soul, 5. Eternal torments, 6. Heaven-going, 7. A supernatural, fallen-angel Devil and Satan, 8. A substitutionary Christ…. The popular churches of Christendom teach some, if not all of the Romish doctrines. Therefore they come under the same condemnation as Rome.
Of course, biblical teaching alone determines what is true and what is false doctrinally. Protestant Christianity can hardly be in error if the above doctrines are established as biblical teaching. Clearly, as we documented in Protestants and Catholics (Harvest House, 1995), Catholic doctrine is unbiblical at many important points, especially the doctrine of salvation. Nevertheless, for Christadelphians, because Protestantism accepts some of the same doctrines as Catholics, it is declared to be just as “iniquitous” and “false” as Catholicism. But obviously, we could apply the same reasoning to Christadelphian beliefs. As we will see, Christadelphian teaching bears certain important doctrinal resemblances to traditional Armstrongism and the Jehovah’s Witnesses: rejection of the Trinity as Satanic; Christ’s atonement for past sins only; the necessity of good works for salvation; the impersonality of the Holy Spirit; a denial of eternal punishment and so on. Would Christadelphians consider it fair of Christians to conclude that Christadelphians were in error solely because of some similarity in doctrine to other religions?
Further, when Christadelphianism rejects Protestantism on the basis of similarity to Catholicism, it uses a double standard. Catholicism also believes in works-salvation, the authority of the Bible and other Christadelphian teachings. But Christadelphians will never classify their own church as “pagan” and “iniquitous” on this basis. So why argue it in such a manner with Protestantism?
Nevertheless, when Christadelphians maintain that “traditional church teachings do not reflect the truth of the Bible in a number of key areas,”  this is precisely what they have never established. Nor can they, since basic biblical doctrine is accepted as established by almost everyone but cultists. Still, as in Mormonism, the Christadelphian church claims that after 1,800 years of apostasy it alone has restored the true gospel. To emphasize this point to the faithful, again as with Mormonism, it attacks the Christian church uncharitably and undeservedly. John Thomas asserted that biblical preachers were the epitome of evil:
What base views must such men have of the God whose ministers they pretend to be! Their “consolations” are unmitigated blasphemy, and false from first to last…. It is the preachers that make men infidels by the preposterous absurdities they preach in the much-abused name of Christianity…. Their ministries have no vitality in them, and leave their flocks in their own predicament, “dead in trespasses and in sins.” Therefore “come out from among them, and be ye separate, and touch not the unclean, and I will receive you, and will be a Father to you, and ye shall be my sons and daughters, saith the Lord Almighty.” 
Citing Galatians 1:8, the Christadelphian Messenger declares that the Gospel Christians teach will only curse those who preach it or accept it. “The conglomerate mixture of Christianity, paganism and assorted doctrines of men preached by the popular churches of Christendom is not the Gospel of Salvation which Christ and the apostles preached, and it contains not enough salvation to save one human soul. It is error, and will accurse all who preach it, and all who accept it.” Christadelphians even argue that Christians are so deceived that they will, at the Second Coming, reject Jesus Himself as the Antichrist:
No one desires to be in the position where he or she might reject Jesus when he comes because of an incorrect understanding of the prophetic events related to his second coming. Yet the framework has already been laid throughout Christianity for most Christians to do exactly that…. This false teaching is preparing millions of Christians throughout the earth to reject Jesus at his return because they will be convinced, by the things he will do, that he is “the Antichrist” and will oppose him.
And Christians will die with a lie on their souls. “Neither Protestants nor Papists ‘believe in God.’ They have a system of faith which bears no affinity to the religion of God; and hence they hope for things which He has not promised; and consequently the most pious of them die with a lie.” Not surprisingly, John Thomas believed that Christian churches do not teach the Gospel:
Let the reader search the scriptures from beginning to end, and he will nowhere find such systems of faith and worship as those comprehended in the Papal and Protestant systems. The gospel of the Kingdom of God in the name of Jesus is not preached among them…. They are dead, twice dead, plucked up by the roots, and therefore the time is come to cut them off as a rotten branch from the good olive tree…. By remaining in them, a man partakes of their evil deeds, and subjects himself to their evil influences.
For Thomas, the Christian churches represented a “thousand-headed monster” that was “devoted to mammon” and the commandments of men, wallowing in “its ignorance of the Scriptures.”
