I'll only need ONE word from you:
Yes or No.
Is the following in force today or not?
"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)
But though we know who is in the Church, but we do not know who is not in the Church.
For instance, we know that every baptized person is in the Church (that includes you and all other FReepers in this discussion, if they are baptized); but we also know someone can have a "baptism of desire" and we don't know who that would be.
We know by name,for instance, that Abraham, Isaac, Jacob, Moses and Elijah are in heaven; they could only have been saved by Christ; therefore they must have been implicitly members of His Church.
That is exactly why the Catholic Church have never stated as a doctrine that any named person is in hell. Only God can judge whether there was an implicit "baptism of desire" in the heart.
Even unbaptized babies' souls, at their funerals in the Catholic Church, are commended not to hell but to the mercy of God. We leave that up to Him.
