I cannot agree with your statement that "To have an Eastern perspective is to have the correct perspective." To have an eastern perspective is to share a mainly Catholic perspective but with some errors; such is a vast improvement over a Protestant perspective which is what Cardinal Gibbons was chiefly addressing in his book Faith of our Fathers. In the Original Post for this thread Cardinal Gibbons makes a very good case for the eastern churches following the lead of the Catholic Church's holy see in Rome.
If an Eastern church had produced
Fiducia Supplicans or been responsible for the Inquisition and the
auto da fe, I might agree with your opinion.
Also the fact we have never had an issue with widespread abuse of children by our clergy such as recently happened in the Roman Catholic Church I think also indicates that there are systemic problems in the RCC.
But the biggest problem is that one Pope can reverse his predecessor, with
Traditiones Custodes, in a manner cruel to traditional Catholics, and also not just Pope Benedict XVI, but Pope St. John Paul II, and then authorize the blessing of homosexual relations, which are not to be blessed but to be anathematized.
In the Eastern churches, decisions are taken according to the principle of Sobornost, or Conciliarity, and the entire church is configured in a way as to resist sweeping changes to the Apostolic faith, as happened with the liturgy under Annibale Bugnini, or more recently, with sexual morality under
Amoris Laetitia and the absolutely unacceptable
Fiducia Supplicans.
Also I would note that the Eastern sui juris Catholic Churches such as the Ukrainian Greek Catholic Churches, owing to their Orthodox liturgical and theological background, have emerged as some of the harshest critics of
Fiducia Supplicans.
Really, the only parts of the Catholic Church I have a highly positive opinion of are the Traditional Latin Mass communities which Pope Francis has harmed so much, and the sui juris Eastern Catholic Churches, and the more traditional monasteries and mendicant orders, such as the Dominicans. The average Ordinary Form parish tends to be beset with liturgical abuses, for example, not using incense on Sundays other than major feast days and not using Gregorian chant as required under
Tra la solicidtudini.
