That’s what happens when you try to be your own Pope. His arrogance will destroy him eventually.
Don't see where he's competing with the Pope.
I think his intentions regarding the founding of his church were sincere and an attempt to get back to "real" Catholicism, but I have to agree with you.
The Catholic Church does provide opportunities for died in the wool traditionalists to celebrate Latin Mass and worship with others of like mind. The FSSP (Priestly Fraternity of St. Peter) and even the Extraordinary Form of the Mass available in many parishes do serve this function. But if one rejects the authority of the Pope these would not be an option.
That's how you end up with denomination after denomination of non-Catholic churches frankly. Wasn't it Martin Luther who said he got rid of one pope and ended up with 300?
