Here's your sources, or two of them anyway, not that Church teaching means anything to you and your made-up religion of opinions.
Pope Gregory X, Council of Lyons, 1274
"We believe that the true Church is holy, Catholic, apostolic, and one, in which is given one holy baptism and true remission of all sins. We believe also in the true resurrection of this flesh, which now we bear, and in eternal life. We believe also that the one author of the New and the Old Testament, of the Law, and of the Prophets and the Apostles is the omnipotent God and Lord. This is the true Catholic Faith, and this in the above mentioned articles the most holy Roman Church holds and teaches. But because of diverse errors introduced by sorne through ignorance and by others from evil, it (the Church) says and teaches that those who after baptism slip into sin must not be rebaptized, but by true penance attain forgiveness of their sins. Because if they die truly repentant in charity before they have made satisfaction by worthy fruits of penance for (sins) committed and omitted, their souls are cleansed after death by purgatorial or purifying punishments, as Brother John 1 has explained to us. And to relieve punishments of this kind, the offerings of the living faithful are of advantage to these, namely, the sacrifices of Masses, prayers, alms, and other duties of piety, which have customarily been performed by the faithful for the other faithful according to the regulations of the Church. However, the souls of those who after having received holy baptism have incurred no stain of sin whatever, also those souls who, after contracting the stain of sin, either while remaining in their bodies or being divested of them, have been cleansed, as we have said above, are received immediately into heaven. The souls of those who die in mortal sin or with original sin only, however, immediately descend to hell, yet to be punished with different punishments. The same most holy Roman Church firmly believes and firmly declares that nevertheless on the day of judgment "all" men will be brought together with their bodies "before the tribunal of Christ" "to render an account" of their own deeds [Rom. 14:10]."
Pope Eugene IV, Council of Florence, 1438.
"It has likewise defined, that, if those truly penitent have departed in the love of God, before they have made satisfaction by worthy fruits of penance for sins of commission and omission, the souls of these are cleansed after death by purgatorial punishments; and so that they may be released from punishments of this kind, the suffrages of the living faithful are of advantage to them, namely, the sacrifices of Masses, prayers, and almsgiving, and other works of piety, which are customarily performed by the faithful for other faithful according to the institutions of the Church. And that the souls of those, who after the reception of baptism have incurred no stain of sin at all, and also those, who after the contraction of the stain of sin whether in their bodies, or when released from the same bodies, as we have said before, are purged, are immediately received into heaven, and see clearly the one and triune God Himself, just as He is, yet according to the diversity of merits, one more perfectly than another. Moreover, the souls of those who depart in actual mortal sin or in original sin only, descend immediately into hell but to undergo punishments of different kinds."
So now I guess, two popes, two councils, and a saint and one of the greatest doctors of the Church are wrong, but your opinion is right.
