It seems to be a pattern in Catholicism.
The Great Schism happened in 1054 AD when the EO split off from the Roman rite over doctrinal issues, with both sides claiming they were the original, one, true church founded by Jesus and the other being in schism.
And then, 500 years later, in the mid 1500's was the Protestant Reformation with Luther addressing the corruption of the Catholic church especially in the area of indulgences. His call was to get back to genuine Catholicism, and for that they ex-communicated him.
And here we are 500 and some years later, with another upheaval within Catholicism over doctrine and corrupt leadership with a group calling for a return to traditional Catholicism.
History is repeating itself.
