During Elizabeth's reign three stages of the development of Puritanism gave occasion for corresponding conflicts with the crown and for making more clear the differences between Anglican and Puritan. During the first decade of the reign, Puritanism meant a protest against certain of the ceremonies and formulas and vestments required of clergymen by the law. The sign of the cross on the child's forehead in baptism, the celebration of saints' days, insistence on kneeling to receive the communion, the use of church organs, the changing of robes during the service, and even the wearing of a surplice or a square cap, were to many earnest souls survivals of "popery" and temptations to superstition.
