Throughout his pontificate, Pope Francis has introduced numerous changes to the life of the Church in the hope of bringing the Church closer to contemporary people. In line with this, he has published several motu proprios on liturgy, aiming to make liturgical life more present in the world. Through his four motu proprios, he offers a new perspective on understanding the liturgy and involves a greater number of laypeople in its reality. Magnum Principium is a motu proprio intended to highlight the importance of translating liturgical books and preparing new ones. It grants local Churches greater freedom in adapting liturgical books to vernacular languages, so that the faithful can better understand the message the Apostolic See wishes to convey. Spiritus Domini is a motu proprio in which the Pope changes the Church’s practice, allowing the ministries of acolyte and lector to be conferred not only to men but also to women, thus fully integrating them into the life of their communities. Antiquum Ministerium is a motu proprio that establishes the ministry of catechist. Catechists have existed throughout the history of the Church, from the early centuries to the present day, but there was no rite for their installation in ministry, nor were they defined as a ministerial role. With this, the Pope gives greater importance to those who perform the ministry of teaching in the Church. Traditionis Custodes is a motu proprio that regulates the celebration of the traditional Mass. With this motu proprio, the Pope aims to limit the celebration of traditional (Latin) Masses to promote unity within the Church. This motu proprio abolishes all privileges for celebrating traditional Masses granted by his predecessors, John Paul II and Benedict XVI.
