"One indeed is the universal Church of the faithful, outside which no one at all is saved, in which the priest himself is the sacrifice, Jesus Christ, whose body and blood are truly contained in the sacrament of the altar under the species of bread and wine; the bread (changed) into His body by the divine power of transubstantiation, and the wine into the blood, so that to accomplish the mystery of unity we ourselves receive from His (nature) what He Himself received from ours."
--Pope Innocent III and Lateran Council IV (A.D. 1215)
This much of Innocent III's bull is true, but is made false when the remainder of the statement is inferred to be doctrine of that true Church, which doctrine is not of the Lord or of /his Church, which exists only in Heaven (Hebrews 12:23,24).
