I wanted to ask: If the catholic church is becoming more worldly, why stay Catholic? Why should I not convert to orthodoxy, since they don't change things up and have still many otherworldly Saints like Saint Paisios and Fr. Seraphim Rose (soon to be saint) which are just different to those in our church?

Believe it or not, the Eastern Orthodox DO change things up. Their Church history has always been very chaotic and their recent Church history is no different. In fact, their Vatican II moment came way back in 1920 when their leaders published an Ecuмenical encyclical. Most, if not all, of the major early Church heresies came from the East (that includes omitting "the filioque") and there is a list I have of many changes, including forged docuмents, which prove the Eastern Orthodox are nowhere near as united and consistent in their beliefs as they claim. Their problems make the internal squabbles of Traditional Catholicism seem like nothing.

I strongly recommend reading articles pertaining to Eastern Orthodoxy in the "original" Catholic Encyclopedia in order to find many of Eastern Orthodoxy's heretical positions.

I remain Catholic because it is the Church founded by Christ upon the Rock of Peter, who alone has the keys to the Kingdom of Heaven.

Just because the majority of Catholics, both clerical and lay, are abandoning the Barque of Peter does not justify us following their lead.  Do not equate the infidelity of the majority as being reflective of the nature and foundation of the Church.  All save a handful abandoned Christ at the Crucifixion. 

Perhaps St. John should have followed the other's lead and abandoned Christ on the Cross because Christ no longer appeared to be who he claimed to be.

The Eastern Orthodox Churches were Catholic and subject to Rome up until 1054, when Patriarch Michael Cerularius broke with Rome. They returned to the True Faith briefly at the Council of Lyons II (1274) and again at the Council of Ferrara-Florence (1439).  The only reason they're in schism now is because the Ottoman Turks took Constantinople in 1453. 

At the fall of Constantiniople, Sultan Mehmet the II immediately set about replacing the Catholic Patriarch (who was in Rome at the time) with the most anti-Catholic man he could find, Genadius Scholarius.  They have been separated from the True Church ever since.  

This unbaptized Turkish Sultan chose the Patriarch, and in a grand public display, handed Genadius Scholarius the symbols of his office.  Scholarius promptly broke from union with Rome, dragging the other patriarchates with him.  This was formalized a few years later in a synod at Constantinople. 

It's worth noting that the last Byzantine Emperor Constantine XI Palaiologos, died as a Catholic.  The night before the fall of Constantinople, there was a great celebration where he celebrated the reunion of the east with Rome (at the Council of Ferrara-Florence).  The next day, he died a glorious death, sword in hand, and subject to the Roman Pontiff.
