I think the Eastern Orthodox church would disagree with you.
until Martin Luther decided that he could do a better job than Jesus in setting up a religion..
Um, no, he was a conscientious Augustinian Catholic monk concerned about corruption in the Roman Catholic Church of which he was a spiritual servant. That the RCC kicked him out rather than deal with what he was saying about holiness is their loss. He was in his way the Donald Trump of his time, and the Establishment wanted him gone.
Bump
Probably not, between the eastern and western church there was a leadership dispute, not a doctrinal one. The Roman church accepts the belief system of the eastern church and vice-versa.
As far as your statement on Luther..he decided to try to reform and challenge the church from without rather than within. The Catholic church has always been able to accept and deal with questions within the confines....however, Luther nailed his opinions on the wall and defied the church to challenge him.....they did.
