@DJRESQ No doubt I didn't write my comment clearly enough for you to get the gist of the REAL problem that needs resolving. Paul VI restarted the ECUMENICAL Council and it is possible that his predecessor had quite validly asked for it to be halted just before he died.
You have not read the binding Document written by Sixtus V linked above. It states that no more than 70 Cardinals can ever be elected (one of which is clearly the Pope himself). When John XXIII died he had (for some odd reason) decided this binding, Canonical Magesterial Law did not apply to himself, and had elected as many Cardinals as he wanted to have. Consequently, at the Conclave that elected Paul VI, there were fully 18 surplus Cardinals which (on the strength of the limitations stated within "Postquam Verus") undeniably reveals that 18 Cardinals participating in the Conclave that elected Paul VI were "Null and Void" and not able to vote in a Conclave.
Firstly. I am a Catholic, I believe in every Law that has been handed down to us in History by every legitimate, validly elected Pope. It is abiding by these Laws that makes us really Catholic. The people who don't want to submit to our Sacred Magesterial Documents are Protestants! We are not allowed to cherry pick which Papal Encyclicals we want to abide by, and which we can throw on the scrap heap. "Not one jot or iota of the Law can be altered" Is Christ's view.. I beg your pardon, but if Pope Sixtus V stated that NEVER can there be any more than 70 Cardinals - He is to be obeyed. If a Pope does NOT obey a Dogmatically binding Law, then he is promised that the wrath of God, St Peter and St Paul will fall upon him. (It's all there in the Document!)
That was the REAL point of my Post. The other issue, ? You make a valid point, but in this case it won't make a difference, since the Pope that re-convened the ECUMENICAL Council was voted into Office by 18 invalid Cardinals (Which is what Pope Sixtus states such men are. Cardinals 1-70 are Valid Cardinals - Cardinals 71-88 on the other hand, are not to be viewed by the Faithful as being Cardinals at all! They are all legally "Null and Void" So how can they vote in a Conclave? Or give us a New Mass? Or Alter the Sacraments, Or alter the position of the Mass Celebrant, Or rob Our Lord's Temples of all their grandeur, (which befits His Majesty) Or bind us to a run of Popes that were invalidly elected?
TBH I don't much like what the document says either - but unlike the majority, I don't stick my head in the sand and hope the reality will go away. We have a new false Church, A new Mass, some very strange un-Catholic Cardinals and Bishops - and the Present Day Pope isn't even a Latin Mass Catholic. According to "Quo Primum" we are not even ALLOWED to have a "New Mass" We can only use (for eternity) The Missal of Pope Pius V. No new Missals.
Once again, being Catholic is HARD, but I'm sure we can do better if we get our heads out of the sand and pray that all will be resolved shortly by Christ.
