Magnae Dei Matris is another encyclical of Pope Leo XIII focusing on the Rosary this one is a bit more indepth than other which are basically asking/reminding people to pray the Rosary in October.
Magnae Dei Matris (Great Mother of God) begins like the other encyclicals on the Rosary saying that at a certain time “occasion arises to stimulate and intensify the love and veneration of the Christian people for Mary”. It then turn to our Heavenly Father, who was the first to love Mary and raised her above all creation naming her his mother. This is key concept of the Encyclical. We in turn must put all of our filial trust in her. Here is where we get the classic pray the Rosary since October is coming up soon, Pope Leo gives some reason why we need to turn to the Rosary in which he mentions public institutions that science and art where there is hardly a mention of God as well as “the consequent laxity and apathy in the practice of the Catholic religion”, this sounds like something that some super conservative would say knocking on the Cafeteria and Secular Christianity that has grown up in the US and Europe. Pope Leo insists that the remedy for this is praying the Rosary. As we pray through the events of Mary’s life we grow closer to Jesus. It goes on and reflects on the idea that Mary is the perfect model of living the Christian life. It continues talking about how constantly praying the Rosary serves piety and is a source of comfort. Eventually the encyclical ends with Pope Leo once again asking (us) his brother bishops to pray the Rosary.
