Although Calvin and Huldrych Zwingli honored Mary as the Mother of God in the 16th century, they did so less than Martin Luther. Thus the idea of respect and high honor for Mary was not rejected by the first Protestants; but, they came to criticize the Roman Catholics for venerating Mary. Following the Council of Trent in the 16th century, as Marian veneration became associated with Catholics, Protestant interest in Mary decreased. During the Age of the Enlightenment any residual interest in Mary within Protestant churches almost disappeared, although Anglicans and Lutherans continued to honor her.
