Many polls indicate that few census Catholics believe in the real presence of Jesus in the Eucharist. This may also explain why so many of the people who once gathered each Sunday to celebrate with us, have not returned after the pandemic. If you do not believe that in receiving the Eucharist you actually receive the bread now become the body of the Lord, and the wine now become the blood of Christ, why bother with joining the community for Mass on Sunday. When you do know God, and do know his desire to be part of our lives, then belief in the true presence of the Lord among us makes perfect sense.
