The Assembly was a product of the British Reformed tradition, taking as a major source the Thirty-Nine Articles as well as the theology of James Ussher and his Irish Articles of 1615. The divines also considered themselves to be within the broader European Reformed tradition. They were in frequent correspondence with continental Reformed theologians, and sought their approval. They also drew upon the pre-Reformation British theological tradition, which emphasized biblical knowledge and was influenced by the Augustinian theological tradition exemplified by Anselm, Thomas Bradwardine, and John Wycliffe. The recorded debates of the Assembly are full of citations of church fathers and medieval scholastic theologians.
