It is noteworthy that much of the opposition to St. Robert's teaching was discredited by the content of the encyclical Mystici corporis. According to this encyclical, "only those who have received the laver of regeneration and who profess the true faith, and who have neither unhappily separated themselves from the fabric of the Body or been cast out by legitimate authority by reason of most serious offenses are to be numbered as members of the Church." [AAS, XXV, (1943), 202.] Thus it presented the teaching of St. Robert as the doctrine of the Catholic Church, set forth officially by Christ's Vicar on earth. Fenton
Any error here?
If Mystici Corporis had not been written, Fenton would still believe what the teaching of St. Robert Bellarmine, which Fenton says was discredited. In the future another decree will come out discrediting Fenton and then another theologian will find yet another way to get the round peg in the square hole (making a non-baptized person a quasi- member of the Church), and say
" It is noteworthy that much of the opposition to Fr. Fenton's teaching was discredited by the content of the encyclical Xinthefuture."
And people like you will then quote the new theologian, and discard Fenton, just like you recently discarded St. Robert Bellarmine's teaching.
