Final answer:
The Ordinary of the Catholic Mass includes liturgical parts such as the Kyrie, Gloria, Credo, Sanctus, and Agnes Dei. Central to the Mass is the celebration of the Eucharist, where bread and wine are consecrated and consumed, symbolizing the Last Supper and establishing spiritual communion.
Step-by-step explanation:
The parts of the Ordinary of the Catholic Mass are essential components of the liturgy that are generally stable throughout the year, as opposed to the Proper of the Mass, which changes daily according to the liturgical calendar. The Ordinary includes the following parts:
- Kyrie (Lord have mercy)
- Gloria (Glory to God in the highest)
- Credo (Nicene Creed - I believe in one God)
- Sanctus (Holy, Holy, Holy)
- Agnes Dei (Lamb of God)
During the Mass, the Eucharist is celebrated, which is based on the words of Jesus during the Last Supper, as He blessed the bread and wine, signifying His body and blood. This sacrament is a vital aspect of the liturgy, with the transformation of the bread and wine into the body and blood of Christ, known as transubstantiation, being a key belief in Catholic doctrine. The Eucharist not only signifies Christ's sacrifice but also serves as a form of communion with God and the community of believers.
