Final answer:
John Wycliffe found some support at Oxford University, although his ideas were eventually condemned by ecclesiastical authorities. Wycliffe challenged Church orthodoxy, and despite some academic backing, was declared heretical by the ecclesiastical council posthumously.
Step-by-step explanation:
John Wycliffe, known for his critique of the Catholic Church and as an early forerunner of the Reformation, did find some support for his beliefs at Oxford University where he had been a professor. Wycliffe's challenges to Church practices such as the sale of indulgences and the wealth of the clergy, and his belief that the Bible should be accessible to all in their own language, found sympathy among certain academics and theologians. However, his beliefs were indeed considered heretical by the ecclesiastical council, as church authorities at the time were keen to maintain orthodoxy and saw his teachings as a threat to their power and control. Ultimately, Wycliffe’s supporters at Oxford were not enough to shield him from being declared a heretic posthumously by the Council of Constance. Thus, the correct answer to the original question 'Which groups did not consider John Wycliffe's beliefs to be heretical?' would be A) His superiors at Oxford University who, at least for a time, provided an environment in which his ideas could be voiced, though not without controversy and risk.
