By Robert Royal, The Catholic Thing - The Pew Research Center, a reliable source on American attitudes about religion, found in 2019 that 43 percent of American Catholics were “unaware” of Church teaching about Christ’s Real Presence in the Eucharist. Twenty-two percent said they knew, but didn’t believe it. Only 28 percent both knew and believed the teaching. And this, as we’re often hearing these days, about what Vatican II called the “source and summit” of Christian life.
