There is no such thing as a protestant church. All are ecclesial communities. The only Christian Churches are the Catholic Church and the Orthodox Church.
Spoken like a True Believer in the self-appointment of Rome!
Sorry, dear FRiend. I will continue to treasure the spoken and recorded words of Christ, when He said, "upon this rock I will build my gathering."
No "churches" appear in the New Testament. Just gatherings.
Churches are buildings. Gatherings require no church buildings. Raise your eyes from the earthly.
