 In 1581, as part of a reaction to the perceived threat of Catholicism, the court signed a "King's", or "Negative Confession", probably commissioned by James VI, that much more harshly denounced Catholicism.The Reformation saw a complete transformation of religious observance.In the place of the many holy days and festivals of the Catholic Church and the occasional observance of the Mass, the single surviving holy day was Sunday and regular attendance and participation was required of the laity.
