Remember: “active participation” means joining in prayer and being engaged with the liturgy that’s happening. It doesn’t, at least according to Rome, require that one be doing the responses.
Now, the idea is everyone is singing the responses, but that’s above and beyond mere “active participation” - it’s not like the Roman Mass in the 50’s at its worst, where no one heard what was going on except the readings, and so would be saying the rosary during mass.
Let me clarify some things about your impression of Mass in the 50s and before. I say before because the Mass was the same for centuries. The 1950s were no different from the 1550s.
And, people have the impression that the Mass before the Council of Trent was different, but it wasn’t. The Council of Trent just codified and unified the Mass.
Creeping embellishments were occuring in different localities, and the Council intended to irradicate them and make the words and rubrics of the Mass identical throughout the Roman Empire. The Council of Trent did not change the Mass. So the Mass of 1950 was the Mass down through the ages back to the Apostles.
Somehow, Catholics were able to fully understand and appreciate what was going on at the Mass for hundreds of years after the death of the Latin language. Any Catholic from 1950 or before could tell you EXACTLY what part of the Mass was being said by the priest and what the words were, at least in paraphrase. If you ever attended a Latin Mass, the priest performs certain actions at each part and it is very easy to discern where he is in the Mass by noting his actions.
All of the greatest saints of the Church loved the Mass, fully participated in the Mass through their silent prayers, completely understood exactly what was happening on the altar, reverenced and adored Christ in the Eucharist, and received His Body and Blood with full knowledge and understanding of what they were doing; as did every Catholic who received the Sacraments of the Church.
The Holy Rosary is a recollection of the Life,Death and Resurrection of our Lord. Saying the Rosary and recollecting these Sacred Mysteries, then going to Communion and receiving His Body and Blood with full knowledge of what this means, **IS PARTICIPATING **in the Mass.
Prior to Vatican II, when several Popes referred to “active participation” , they were referring exclusively to the singing of Gregorian Chant by the people.
The Pope has said: Yet active participation does not preclude the active passivity of silence, stillness, and listening: indeed, it demands it.
So when you disparage the quiet reverence of the old ladies in babushkas of the 50s saying their beads at Mass, I have to assert my firm conviction that they were much closer to God by praying in silence, and solemnly and reverently receiving Communion at the rail, than anything that’s going on at the Mass of ‘full participation’ today.
