Arminianism vs. Arianism and the Church of England

Whitefield vehemently argues against Arminianism in his sermons, particularly in "The Lord our Righteousness" sermon. Wesley staunchly argues against Arianism in his sermons. Both of these men are Anglican clergy and preach within the Anglican tradition. This doctrinal dispute exists within the walls of Anglicanism, which leads me to my question(s): What is the role of the Anglican Church in this debate? Is there record of other church leaders weighing in? Does the Anglican Church have an official stance supporting one doctrinal belief over another at this point in history? Do the conflicting perspectives between Whitefield and Wesley reflect a larger historical tension within Anglicanism? It seems this doctrinal difference among Anglicans is significant enough to lead those leading toward Arminianism to start a new church (Methodism). Since it was such an important difference, I'm just wondering if the Anglican church had an "official" doctrinal stance towards it (I'm not that familiar with Anglican doctrine, so forgive me if there is an obvious answer to this question).
