“O that men could be induced now to devote themselves to the study of the scriptures without regard to articles, creeds, confessions, and traditions! These things are mere rubbish; monuments of the presumption and folly of former generations indoctrinated with the wisdom from beneath. If a Berean spirit could be infused into them; if they could be persuaded to “search the scriptures daily” for the truth as for hid treasure; they would soon leave their spiritual guides alone in all their glory of mysticism and patristic lore, and rejoice in the liberty of that truth which can alone make them “free indeed”.” 
JT was not a man for creeds. He certainly nails the risk of such documents – elevating them as the means to interpret scripture, expositing them word for word and applying them to questions which they were not designed. Sure, they have a value (as we talked about here). But the founder of the Christadelphians was pretty blunt about their limitations and priority.
