In order for any of the things Christadelphians believe to be true, the first and foremost fact of all facts must be that the Bible is the wholly inspired and infallible Word of God. Therefore, the preamble to the Christadelphian Statement of Faith reads:
THE FOUNDATION.--That the book currently known as the Bible, consisting of the Scriptures of Moses, the prophets, and the apostles, is the only source of knowledge concerning God and His purposes at present extant or available in the earth, and that the same were wholly given by inspiration of God in the writers, and are consequently without error in all parts of them, except such as may be due to errors of transcription or translation.
Interpretation was not a private matter left to the discretions of the writer, but a matter in which men specially selected by God were moved by the Holy Spirit. If the things we believe contrast the things spoken of in the Scriptures, it is not the writers of the Scriptures who have erred, but ourselves in coming up with some wrong idea. If there appears to be a contradiction, we must understand that there is no contradiction possible, but only a lack of perception on our part to see the matter clearly.
While it is true that certain English Language translations have mistakes due to translators, this is not the fault of the original writers. With the volume of works available today dealing with the ancient manuscripts, it is not difficult to get the correct understanding of any passage, regardless of translation.
