The message judges the messenger
Paul warns that corrupt teaching can arise among leaders and requires even an apparently authoritative messenger to be tested against the gospel already received. Longevity, office and influence do not remove the need to examine what is taught.
Read Scripture as a connected whole
The New Testament fulfils and explains the purposes set out in Moses and the prophets. Following promises, covenants and themes across both Testaments helps us test a doctrine more carefully than collecting isolated phrases.
Use history without making it infallible
The historical transmission and recognition of Scripture matter. They do not automatically prove every later claim made by institutions that preserved or interpreted it. Equally, the mistakes of particular leaders do not by themselves refute every claim a church makes. The precise claim and its evidence must be considered.
The Berean habit
Acts 17:11 commends people who receive the message eagerly and examine the Scriptures to see whether it is true. Receptiveness and testing belong together. A useful reading habit is to identify who speaks, who is addressed, the problem being answered and the argument surrounding a disputed phrase. Then follow the relevant theme through the wider Bible. This gives a doctrine more support than a list of verses whose contexts are left unexplained.
Continuity does not remove accountability
Acts 20:28–32 warns overseers that destructive teaching can arise among them. Revelation 2–3 addresses real communities with real standing, yet calls them to repent of doctrinal and practical failures. These passages show that an established congregation is still answerable to Christ. They do not prove that every historical institution failed in the same way. They establish the principle that recognised leadership and an inherited name cannot make examination unnecessary.
What about apostolic tradition?
Second Thessalonians 2:15 tells believers to retain what the apostles taught, orally or in writing. Second Timothy 2:2 requires transmission to faithful teachers. We affirm that the original message had both forms. The question about a later tradition is whether it preserves that message. A succession of offices can transmit truth, but the succession alone cannot demonstrate the apostolic origin of each later doctrine attributed to it.
Apply the same test to ourselves
A Christadelphian statement of faith, an ecclesial decision and a book by Roberts all remain subject to Scripture. Reading an expositor well means following the passages and reasoning rather than inheriting the conclusion solely because of the author’s reputation. When two readings conflict, state each fairly, identify where their explanations differ and return to the text. The aim is not endless doubt, but a conviction whose reasons can be examined.
Questions & responses
Why read Roberts if Scripture is the authority?
An exposition can help organise evidence and ask useful questions. We read Christendom Astray in that role. Neither Roberts, another historical writer, nor a modern fellowship replaces Scripture as the final test.
