No, besides deviations from the NT church , they were not all Roman Catholic, nor was the Peter of Scripture that of Rome . Even your Catholic brethren affirm such a distinction, among other significant differences. They were not even Catholic as the thirteenth or nineteenth century world would have understood the term. Nor is apostolic succession established in Scripture.
Which has overall been shown on this thread or others, but if you want to debate this let me know.
Obviously we disagree and I’m sure you understand my skepticism when reading things written by non Catholics.
I am certainly aware of the arguments for and against the Church and have been led by the Holy Spirit to accept the Church.
Thank you for sharing your insights, dear brother in Christ!
