You can't make this shit up. The church really stands behind this. I have not studied it but I did encounter it.

"9. The Lord’s words at the last supper, ‘Take and eat; this is my body’, do not allow us to dissociate the gift of the presence and the act of sacramental eating. The elements are not mere signs; Christ’s body and blood become really present and are really given. But they are really present and given in order that, receiving them, believers may be united in communion with Christ the Lord."
