I reject your lame premise and trap. It’s Dishonest and childish. The pope is the vicar of Christ and head of all Christians in communion with Rome. Only those who are cats or orthos are true Christians. Orthodox are true Christians as their churches and traditions were founded by the apostles after Pentecost.
If you are a prot you are just making up a version of Christianity by your own design.
You are your own pope - a self centered self submitting one.
If your name was Mike and you were a prot of any denom then you would be a “mike-ist” (As in Luther=Lutheran, Calvin=Calvinist). Mike likes a little Calvin a little Knox a little Aquinas a little cormac McCarthy His uncle was smart so he likes that too.
Mike stirs that up reads the Bible interprets it the way he sees fit and calls himself a true Christian. He after all doesn’t follow a pope! HE knows what’s best! And if you disagree? Well that’s the Holy Spirit! Isn’t that convenient! If he doesn’t have an answer that’s satisfying to himself - mike just goes to a YouTube celeb a speaker A philosopher or theologian he likes and adopts that as his explanation. At the end of the day mike is his own pope submitting to mikes own biases mikes own experiences and mikes own itching ears.
Christians, true followers of Christ, can also be found in Protestant denominations. Church discipline and submission to religious authority is well established in some mainline Protestant denominations and in some non-denominational, biblically orthodox (little o) congregations. Additionally, the Westminster Catechism of Faith provides no short list of guard rails on the interpretation of Scripture.
Furthermore, I am well familiar with the teachings of the Roman Catholic Church as I was raised and confirmed a Catholic Christian. My journey of faith in Christ included a departure from Catholicism during my undergraduate studies. I could not reconcile how some extra-biblical Catholic teachings seemed to be in direct conflict with Scripture-based truth.
For example, was it also people with itching ears who first forbade Catholic priests from marriage? This conflicts with the Apostle Paul's words to Timothy, "Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons, through the insincerity of liars whose consciences are seared, who forbid marriage..." (1 Tim 4:1-3a).
