This article deals with the issue of the liturgy of the Mass in 1965. This form of celebration is a direct result of the Constitution on the Liturgy of the Second Vatican Council. Unfortunately, due to the pace of post-Council changes, the problem raised has not received much research. However, the liturgy of 1965 is important insofar as it represents the springtime of the Church’s liturgical renewal. This article presents the liturgical renewal of the Mass, showing the relationship between the changes and the decisions of the Constitution on the Holy Liturgy, which allows us to discern the hermeneutics of continuity between the Missal of John XXIII and the Missal of 1965.
