Bullinger is full of Bull and has no authority. His opinion is certianly not more worthy of more merit than for example, St. Ignatius of Antioch:
Even a cursory reading of the still extent letters of St. Ignatius, Third Bishop of Antioch (A.D. 110) reveal that the Roman Church and the Greek orthodox Church have retained the true nature of the Apostolic Church.
St. Ignatius presents a clear view in his letters of the catholic, hierarchical and monarchical structure of the very earliest Church: (quote)
“Where the Bishop is, let there the people be, as where Jesus is, there is the Catholic Church”.
Ignatius commented extensively on the True Presence of Christ in the Eucharist.
Don’t heed the errors of the later protestant revisionists of history; read St. Ignatius 7 letters firsthand.
What gives Ignatius more authority than Bullinger? Are you aware that the so-called letters of Ignatius of Antioch are considered forgeries by many? See The Ignatian Forgeries. There is adequate evidence that what some believe are genuine letters from Ignatius are really forgeries written at least a century or later after his lifetime. From the link above:
Shouldn't we ALL be under the authority of Scripture rather than individuals no matter how far back they supposedly go?
