Under Edward reform ideas that were suppressed during Henry's reign were receiving more of a receptive ear. In particular Thomas Cranmer followed Luther in setting an order of worship that all could understand. Mary I tried to turn England back to Roman control, but her life was cut short in 1558. However she was successful in exiling many of the leaders of the Church of England to the European continent who did not want to return to Roman Catholic. Elizabeth I was next in line to make an attempt at settling the controversies that had formed in England. Her main idea was for everyone in England to recognize the thrones supremacy of the church and renounce anything to do with Rome. During her reign, many of those who went into exile came back and began to teach at Oxford and Cambridge. These people had turned to many Calvinistic views while away on the European continent, and began to spread them in their teaching. Their beliefs were to use the scriptures as the foundation for beliefs, pretty much if it was in the scriptures; it was to be done but if not it wasn't. Their concerns with the Church of England were that the clergy was huge on piety and morals, but lacked the doctrinal knowledge needed to preach the Word. They thought the believers practiced too closely the ceremonies of medieval Roman Catholicism. If that was not bad enough, they also took time on the Sabbath for many recreational activities in the place of scripture reading and spiritual upliftment. It is these groups, which began to be derogatorily called Puritans. Upon Elizabeth's death, James I came to the throne and would have nothing to do with the even more assertive Puritans, so he would have their more vocal leaders put away. This scared some off to the Calvinist Netherlands and some to New England. Soon after these groups came to the Americas, Charles I had another group of Puritans come called the non-separatists.
