You keep saying “One true Church”...you must be referring to Eastern Orthodox (Greek Orthodox, Armenian Orthodox, Serbian Orthodox, etc.), not the Pope-lead, Pope as ultimate authority, Pope chosen by the Holy Spirit thru the College of Cardinals splinter church in Rome. The Roman Pope has “plenitudo potestatis”...if you “disrespect”/criticize your Pope you are blaspheming your church.

No; that’s not what I’m referring to.
The churches you mentioned are all schismatic.
