ORANGE COUNTY, Fla. -- A University of Central Florida student, upset religious groups hold church services on public campuses, is holding hostage the Eucharist, an object so sacred to Catholics they call it the Body of Christ.

Cook claims he planned to consume it, but first wanted to show it to a fellow student senator he brought to Mass who was curious about the Catholic faith.

"When I received the Eucharist, my intention was to bring it back to my seat to show him," Cook said. "I took about three steps from the woman distributing the Eucharist and someone grabbed the inside of my elbow and blocked the path in front of me. At that point I put it in my mouth so they'd leave me alone and I went back to my seat and I removed it from my mouth."

A church leader was watching, confronted Cook and tried to recover the sacred bread. Cook said she crossed the line and that's why he brought it home with him.

"She came up behind me, grabbed my wrist with her right hand, with her left hand grabbed my fingers and was trying to pry them open to get the Eucharist out of my hand," Cook said, adding she wouldn't immediately take her hands off him despite several requests.

Regardless of the reason, the Diocese says its main concern is to get the Eucharist back so it can be taken care of properly and with respect. Cook has been keeping the Eucharist stored in a plastic bag since last Sunday.
