If that were true, then why is St Ignatius, who holds the office that would later be called “Patriarch” of Antioch, writing multiple letters to people in cities under the jurisdiction of other bishops? If there were no higher rank than bishop, he would be committing grossly inappropriate interference in the local churches ruled by other bishops.
You make a good point Petergee. For those who will only believe what is written in scriptures, we also find it was a unified, universal, Church.
Act 15:22 Then it pleased the apostles and ancients, with the whole church, to choose men of their own company and to send to Antioch with Paul and Barnabas, namely, Judas, who was surnamed Barsabas, and Silas, chief men among the brethren.
Act 15:23 Writing by their hands: The apostles and ancients, brethren, to the brethren of the Gentiles that are at Antioch and in Syria and Cilicia, greeting.
Act 15:24 Forasmuch as we have heard that some going out from us have troubled you with words, subverting your souls, to whom we gave no commandment:
Act 15:25 It hath seemed good to us, being assembled together, to choose out men and to send them unto you, with our well beloved Barnabas and Paul:
Act 15:26 Men that have given their lives for the name of our Lord Jesus Christ.
Act 15:27 We have sent therefore Judas and Silas, who themselves also will, by word of mouth, tell you the same things.
