Fr. Corapi said that he was thrown out of the first order he joined. The unrest began when he discovered sacred vessels in the sacristy, that had not been purified. He went on to explain that visible particles - even one drop of precious blood - meant that Jesus was still present. One by one, he would purify the sacred vessels, each and every day. He spoke with the other members who agreed in transubstantiation but claimed that Jesus was only present during the Mass. He called them on this, explaining the error in their thinking (he has 5 degrees - the maximum one can obtain - in the Church. They disregarded his teaching. The following week, after purifying the vessels again he gathered all the candles he could find, and lined them up in the sacristy, where he knelt down in prayer. He felt that such revilement required a Holy Hour. While at prayer, the Director of the Order confronted him in the sacristy. Within a matter of days, he was tossed out from the Order.
This tidbit was included in his presentation on the Holy Eucharist.
I watched Fr. Corapi on EWTN last night. Loved that story. I can just picture his reactions when he first found out about the heresy being committed.
