Yes, if I desired to do the research I could post that. However, I am not sure what good any of that does. In truth, anyone who looks around the state of the Church in the USA, Canada, and Europe, has little doubt that belief in the Real Presence has plummeted, along with belief in a great many things. Catholics abort in high numbers, they contracept at close to the same rate as the general population, they live together, they fornicate, they do nearly all the same things that the general population does, and Mass attendance has plummeted in the same period that Catholics have walked away from their faith.
All of these “things” mirror each other. If Catholics believed that the Eucharist is truly Jesus/God, than they would not do a great many things they do. Further, if a majority of Catholics believed that the Eucharist is truly Jesus/God, than weekly Mass attendance rates would not not be in the 25-30% range (which is the exact mirrior of the Gallup Poll reflecting only 30% of Catholics believe the Eucharist is truly Jesus/God). In the 40s and 50s, Mass attendance was around 74%, with more strict pre-Mass fasting regulations and more Holy Days of Obligaton.
Belief in the Eucharist as being truly Jesus’ Real Body, Blood, Soul, and Divinity, is something that transforms and converts people–Catholics who believe the Eucharist is Jesus/God will think twice before getting abortions, divorcing, living together, etc…it is all linked together and it all mirrors each other.
Finally, if belief in the Real Presence were held by say 80% of all Catholics, than confession lines would be stacked full (like they used to be back in the days of 74% Mass attendance).
All one has to do is to take a look at the practices of lay Catholics to understand the truth.
