Pope Gregory XVI condemns Innovators who would “Renew” the Church
The ideas of the Vatican II revolution weren’t new in the 1960s. In the post-Reformation period, various errors along the lines of Liberalism and Modernism had already infected sundry innovators who were trying to introduce these novelties into the Church. The errors manifested themselves in revolutionary movements to bring the Church “up to date”, introducing vernacular tongues into the sacred liturgy, changing the Mass to correspond more to the demands of modern man, adapting Church discipline to modernity, etc.
The Holy See, of course, always sternly and competently condemned these errors and defended the Immaculate Bride of Christ from the snares of the innovators.
