On The Most Holy Sacrament Of The Eucharist, Canon IV
ON THE MOST HOLY SACRAMENT OF THE EUCHARIST
CANON IV.-If any one saith, that, after the consecration is completed, the body and blood of our Lord Jesus Christ are not in the admirable sacrament of the Eucharist, but (are there) only during the use, whilst it is being taken, and not either before or after; and that, in the hosts, or consecrated particles, which are reserved or which remain after communion, the true Body of the Lord remaineth not; let him be anathema.
