The Church is One Mystical Person of Christ and Body in a supernatural union of Grace by the Indwelling of the Holy Spirit in three states: of blessedness in Heaven, of purification after death, of visible communion on earth. This means that Christ dwells in all and only in all that comes from Him (what He joins to Himself), but not in any of what contradicts Himself. This is why there can not be a facile identification of the Church with its visible members with all the actions of all or any of its members. All that comes from the sin of its visible members, of course, is not the Church, because it departs from union with Christ. The opposite distortion is the too often heard “we are the Church” materially understood as one would of any other sociological grouping of humanity, which is a radical secularization of a Divine Mystery. This is why one can say that every member of the Visible Church sins, but the Church does not sin. Thus in the Holy Father’s “apology” we see clearly that he does not identify the Church herself with the sins of which her sons and daughters, however lofty their position, have committed.
Thus the Church is holy, not sinful as its members are (taken individually or materially, for there are many dead members of the Visible Church who are only materially, i.e., externally, joined to the Church and to Christ, who nevertheless have the opportunity of being revived, especially by the prayers and sacrifices of the alive members.)
