This article attempts to contemplate, in a brief overview, how the liturgy in the Petrine Magisterium is presented today, on the tenth anniversary of his pontificate. The apostolic letter Desiderio Desideravi presents the concept of liturgy as being the today of salvation history. To truly live this divine gesture, the pope invites everyone to celebrate the sacred mysteries in a simple and sober way. The letter presents the liturgy as a meeting place, where a merciful and welcoming dialogue takes place and where the faithful are called to the mission. These elements that appear in the apostolic letter are present in the writings and pontificate of Pope Francis. The present work traces an itinerary of these concepts through some of the main writings of Pope Francis, and how they relate to Church worship, until their use to define the Liturgy according to Desiderio Desideravi. In this way, it is possible to observe the great current challenges to the application of the liturgy and to seek, through the means of liturgical education, to lead the brothers to that full participation in the liturgy so desired by the Church.
