Thank you for your honesty. I was getting tired of the response “because the Pope said so” as that answers nothing for me.
Your point that it was to hopefully bring more faithful to the Mass is valid and something I believe. I wonder your thoughts on also if the removal of the communion rail was also something done for that cause? I am slowly learning as I go but to me what seem to be needless removals from Mass (communion rail, certain prayers) are to others normal. I guess we never stop learning.
I had to reflect for the first sentence: For Catholics the Pope is the vicar of Christ, his voice is the one which primarily counts.
St Pius V froze the Liturgy (except the actual calendars) this was gradually opened beginning St Pius X.
The Tridentine Mass made the laity mere spectators, listeners, and practically in may times only the ones present only without any participation. They prayed the station of the cross, the rosary, sung hymns loosely related to the mass, or read the words of the missal, while the priest and only the priest with minimal help of the servers celebrated the Mass.
In my time everyone saw that it is wrong, active participation needed. To promote this the prayers/chants of the laity became part of Mass, and the faithful were taught to understand the mass. This required the simplification, the removal of the duplications, illogical sequences (e.g. Ita Missa est them a series of important looking prayers) and so on.
The pope (Paul VI) said so, that this is good and necessary, and if you what carefully how the TLM masses make everything to get the laity involved. I my time in every parish there was only one Missa Cantata in a weekend, the second was allowed only for a funeral on the day of the death. Now in my traditional Church out of three Masses three are Missa Cantata, yesterday even all with incense; and even the weekday masses are closer to the Missa Cantata than to the Low Mass.
The communion rails is different problem. When I left Hungary in 1981 the communion rails were intact, there was confession before each mass and less than half of the participants received the Blessed Sacrament naturally kneeling at the rails and to tongue.
When I arrived here in 1982 everyone was herded to the communion. And what is worse, there was no opportunity for confession. The ‘everyone lined up for communion’ required the removal of the rails and the receiving by standing, this can be distributed and made in the fraction of time. This was not the will of the pope, the popes (Paul VI and John Paul II) were practically forced to allow it.
The essential change was herding everyone to the communion, and I believe that was deliberate action by the modernist
As far as I know even traditional churches follow this trend, the concept of the mortal sin is redefined at least tacitly. May be this is the truth and the Eucharist is food for saints and sinners alike.
