Encyclical of Pope Pius XII
|Signature date||20 November 1947|
|Number||12 of the pontificate|
The encyclical suggested new directions and active participation instead of a merely passive role for the faithful in the liturgy, in liturgical ceremonies and in the life of their parish. The encyclical also emphasized the importance of the Eucharist. Mediator Dei is one of the more important encyclicals of Pope Pius XII. The encyclical condemned certain excesses of liturgical reform and stressed the importance of the union of sacrifice and altar with communion, which would also be seen in the reforms undertaken during and after Vatican II. It was written in part in response to the liturgical movement under way since early in the 20th century.
