Catholics believe that the Eucharist is the Body and Blood, Soul and Divinity of Christ. Aquinas called it the perfect symbol -- the symbol which is what it signifies. Catholics who believe otherwise are heretics.
Does that mean they are not really Catholics??? Or Christians??? Does your church have a position on this???
Every thing I read says that only 30% of Catholics believe in the presense of Jesus in the Eucharist...That would surely shrink the size of your church if they are not actually Catholics and/or Christians...
