Part 1: The 8 Ecumenical Fathers

Ever since I became Catholic, I’ve heard the title “Doctor of the Church” tossed about… but rarely have I gotten any further in my imagination than “that means he (or she) was really important.”

But what does it mean to have been given the designation “Doctor of the Church,” and why should regular Joe-Catholics care if they’re not studying to be theologians or youth catechists?

Why should you care?

We should all care because the Catholic Faith is a pearl of great price. It’s an absolute treasure. Martyrs have died. Persecutions. Much blood and ink has been spilled in elucidating and preserving the faith in all its precisions and distinctions to this day. We are but the beneficiaries – standing on the shoulders of giants. Whether you are Catholic by virtue of your birth or by conversion, everything we possess is a depository, through God’s grace and providence, of the work and prayers of those who came before us. To not care is like saying, “Meh, I don’t really care that I was born with two legs, or with the faculty of eyesight, or with fresh air to breathe.”

So, while you need not go read volumes or sign up for a Licentiate degree in Rome, we hope this series helps as a resource and a basic primer on our awesome patrimony.

What does the label mean?

The title “Doctor of the Church” is officially “bestowed by the Pope in recognition of the outstanding contribution a person has made to the understanding and interpretation of the sacred Scriptures and the development of Christian doctrine” (c/f Dr. Marcellino D’Ambrosio).

The Church comes to the determination that each of the following three qualifications has been met in order to merit this great title:

1. Preeminent holiness, even among saints

2. Depth of doctrinal insight

3. Extensive writings which the Church can recom­mend in any age of history as an expression of authentic Catholic Tradition
