It was first published in 1965 by the Consilium for the Implementation of the Constitution on the Sacred Liturgy (Consilium ad exsequendam constitutionem de sacra liturgia) to provide the Holy See's official documents along with commentary, scholarly articles, new liturgical texts, reports of meetings, responses to dubia, and the speeches of the Pope on matters having to do with the liturgy of the Roman rite.

In 2004, the journal's subtitle was shortened to simply Commentarii. In 2016 it switched to an online-only publishing model and yearly periodicity, and the following year scans of past issues were made available.
