When Edward came to the throne, Cranmer was able to promote major reforms. He wrote and compiled the first two editions of the "Book of Common Prayer", a complete liturgy for the English Church. With the assistance of several Continental reformers to whom he gave refuge, he changed doctrine or discipline in areas such as the Eucharist, clerical celibacy, the role of images in places of worship, and the veneration of saints. Cranmer promulgated the new doctrines through the Prayer Book, the "Homilies" and other publications.
