They tend to operate organisationally fairly similarly, although there are different emphases. Despite their differences, the Central, Old Paths, Dawn and Berean fellowships generally subscribe to the "Birmingham Amended Statement of Faith" (BASF), though the latter two have additional clauses or supporting documents to explain their position. Most Unamended ecclesias use the "Birmingham Unamended Statement of Faith" (BUSF) with one clause being different. Within the Central fellowship individual ecclesias also may have their own statement of faith, whilst still accepting the statement of faith of the larger community. Some ecclesias have statements around their positions, especially on divorce and re-marriage, making clear that offence would be caused by anyone in that position seeking to join them at the 'Breaking of Bread' service. Others tolerate a degree of divergence from commonly held Christadelphian views. While some communities of Christadelphian origin have viewed previous statements of faith as set in stone, others have felt it necessary to revise them in order to meet contemporary issues, update language or add supporting Biblical quotations.
