I used the substance/accident formulation hesitantly, because I knew it might be read incorrectly. I was getting at the changes implied in Sacrosanctum Concillium :
Ah! I agree we can talk about there being essential components and accidental components of the Mass (in all its forms/uses in the Roman Rite), and we could probably take a step back and even say there are essential and accidental components of the “Mass” in all the rites of the Church, but then we could also take a step forward and speak of essential and accidental components of the various forms/uses of the Roman Rite itself, which is what I misunderstood you to be speaking about. The triplicate Kyrie, the longer Confiteor, the Prayers at the Foot of the Altar, the Last Gospel, etc. are all essential components of the Extraordinary Form of the Roman Rite in as much as we can actually distinguish the Ordinary Form from the Extraordinary Form by the former’s lack of such essential elements!the liturgy is made up of immutable elements divinely instituted, and of elements subject to change. These not only may but ought to be changed with the passage of time if they have suffered from the intrusion of anything out of harmony with the inner nature of the liturgy or have become unsuited to it.
