It firmly believes, professes, and proclaims that those not living within the Catholic Church, not only pagans, but also Jews and heretics and schismatics cannot become participants in eternal life, but will depart “into everlasting fire which was prepared for the devil and his angels” [Matt. 25:41], unless before the end of life the same have been added to the flock; and that the unity of the ecclesiastical body is so strong that only to those remaining in it are the sacraments of the Church of benefit for salvation, and do fastings, almsgiving, and other functions of piety and exercises of Christian service produce eternal reward, and that no one, whatever almsgiving he has practiced, even if he has shed blood for the name of Christ, can be saved, unless he has remained in the bosom and unity of the Catholic Church.
The infallible pronouncements of
Cantate Domino have been mocked for some time.
It says that pagans and Jews are not living within the Catholic Church, and that they are consigned to hell unless before their death they are joined to the Catholic Church.
If a Jew (by way of example) could be actually joined to the Catholic Church while remaining a Jew ,
Cantate Domino is a lie, and the “infallible” Catholic Church lied. If a Jew could be “within the Catholic Church,” CD couldn’t have said Jews are “not living within the Catholic Church” - yet it did.
Their is so much sophistry committed in trying to reconcile CD with a view that Jews (again, by way of example) can be saved while remaining Jews that one can only shake one’s head with disgust.
Forked tongues abound.
But this is nothing new:
"The Jews, as a nation, are objectively aiming at giving society a direction which is in complete opposition to the order God wants. It is possible that a member of the Jєωιѕн Nation, who rejects Our Lord, may have the supernatural life which God wishes to see in every soul, and so be good with the goodness God wants, but objectively, the direction he is seeking to give to the world is opposed to God and to that life, and therefore is not good. If a Jew who rejects our Lord is good in the way God demands, it is in spite of the movement in which he and his nation are engaged.”
Fr. Denis Fahey, The Kingship of Christ and the Conversion of the Jєωιѕн Nation (1953), p. 52
The Catholic Church is being chastised by God, just as the Jews were under the Old Covenant.
