We have enough words about the the Church’s doctrines and dogmas on the Real Presence. No more words that no one will read.
The problem is the Praxis in the manner the Mass is celebrated today.
1. Casual, sloppy liturgies
2. No attention to detail
3. Ad libbing
4. No meaningful Eucharist Fast, I recommend recovering the 3 hour fast before Mass
5. Communion standing, in the hand, on the run.
#5 the biggest reason for loss and continued loss of belief in the real presence. There were no major issues with orthodox belief, Catholic piety, reverence and wonder and awe in the pre Vatican II Mass. What changed is the problem.
