What was the basis of the speech Winthrop gave his fellow passengers aboard the Arabell?

Winthrop's words laid out specific guidelines for living together in a Christian community—an important message because many of the settlers came from different regions and did not know each other before the journey. Winthrop also cautioned that the world would be watching them, and that failure to fulfill their duty to God would not only ruin their chances of prosperity, but would also disgrace like-minded Christians across the globe.
