What This Free Course Covers

In this free course, David Bercot examines several doctrines and historical claims that often divide Protestants from Roman Catholic, Eastern Orthodox, Coptic, and similar churches. The lessons ask whether teachings about Mary, apostolic succession, icons, incense, prayers to saints, papal authority, and the seven ecumenical councils are found in the New Testament and in the earliest Christian writings.

Bercot repeatedly frames the issue around the apostolic faith as something once delivered, then compares later church claims with Scripture and selected early Christian sources. The course moves from specific devotional doctrines, such as beliefs about Mary and prayer to saints, to larger institutional claims, such as succession, Rome’s authority, and Eastern Orthodox appeals to the councils.

It is designed to help students understand the arguments behind these claims and to evaluate them historically and biblically.

  • What kind of apostolic succession is Bercot evaluating?
  • Does the New Testament describe a required chain of ordination?
  • Were bishops and presbyters originally distinct offices?
  • How does Paul’s apostleship affect the argument?

  • What is Rome’s claim about Peter and the bishop of Rome?
  • How does Bercot interpret the evidence about Peter in Rome?
  • Does Peter’s prominence among the apostles prove papal authority?
  • What does the lesson say about ecclesiastical titles?

The Myth of the Seven Ecumenical Councils

  • Why does Bercot call the seven ecumenical councils a myth?
  • How did imperial power affect the councils discussed in the lesson?
  • Why do different churches recognize different numbers of councils?
  • What does the lesson say about returning to the apostolic faith?

David Bercot provides a good starting point in dismantling the claims of the Roman Catholic and Eastern Orthodox claims with the evidence from Scripture and early church writings. We can be confident that those two, as well as similar traditions like the Coptic church, do not hand down the faith which Jude says was once for all delivered and Irenaeus said could not be improved upon. I would add one more historical point to dismantling the Myth of the 7 ecumenical counsels. The 6th counsel, which posthumously dogmatized the teaching of Maximus that Christ has two "wills" as defined by a…

This course was very informative. I've talked with many Roman Catholics, the everyday Catholics, the ones in the pews, and they are highly suspicious of the Bible unless it is being interpreted by the Church. They have a strong belief that only the Catholic Church, through the Magisterium to the Pope are the only ones to tell them right from wrong and how to live and worship. My experience is that they simply won't believe anyone else. I've heard them actually pray, "Mary save us." It’s really terribly sad, they are wonderful, kind people. May we all pray that God would open their…
