On the first week of the Bread of Life Discourse, I noted that we would not celebrate the Twentieth Sunday in Ordinary Time because the Solemnity of the Assumption of the Blessed Virgin Mary supersedes it in liturgical rank. How is this determined? We delved a bit into the liturgical calendar in mid-July, but here we will explore it a bit more.
Generally speaking, there are four ranks of liturgical days. From highest to lowest these are: solemnity, feast, memorial, and ferial. Within each of these ranks, there are sub-rankings. For example, some solemnities are more important than others. This is the case with today’s celebration: while each Sunday in Ordinary Time is a solemnity, Solemnities of the Lord, Mary, and Saints are ranked higher. When two feasts coincide, whichever feast ranks higher is the one that is celebrated. There are also cases where a Feast of the Lord, such as the Presentation on February 2 or Transfiguration on August 6, outranks a Sunday in Ordinary Time. All of these precepts are designed to help us enter fully into the life of our Lord, the life of his Church, and celebrate his Sacred Liturgy where he reveals his paschal mystery in the Church’s celebration. This table shows the ranking of liturgical days and how it is determined what is celebrated.
