 On 6 July , they received a set of rules from Parliament and were ordered to examine the first ten of the Thirty @-@ Nine Articles , the current doctrinal standard of the Church of England , and " to free and <unk> the Doctrine of them from all <unk> of false <unk> " . After a day of <unk> , the Assembly took a vow , as directed by Parliament , to " not maintain any thing in Matters of Doctrine , but what I think , in my conscience , to be truth " . The divines organized themselves into three standing committees , though each committee was open to any member of the Assembly . The committees would be assigned topics and prepare propositions for debate in the full Assembly following each morning of committee meetings . In addition , over 200 ad hoc committees were appointed for tasks such as examination of candidate preachers , college fellows , and suspected heretics .
