BALTIMORE – The U.S. bishops added their assent to a call to have St. Irenaeus declared a doctor of the church.

The action came November 12, the second day of their November 11-13 fall general meeting in Baltimore.

“This is perhaps a way to correct an oversight of history,” said Bishop Kevin C. Rhoades of Fort Wayne-South Bend, Indiana, chairman of the U.S. bishops’ Committee on Doctrine.

St. Irenaeus was born sometime between A.D. 120 and A.D. 130 in Smyrna in Asia Minor, according to Bishop Rhoades. He was a disciple of St. Polycarp, who was himself a disciple of St. John the Apostle, he added. He died around 202, and the Catholic Church also deems him to be a martyr.

St. Irenaeus’ ministry took him to present-day France. There, he waged theological battle against the Gnostics, who emphasized personal spiritual knowledge over faith in orthodox teachings and in ecclesiastical authority. This is relevant, Bishop Rhoades said, because “we see a reemergence of gnostic ideas and what it means to be human.”

The saint, he added, “consistently upheld the unity of God in three persons, the unity of salvation and the unity of the church.”

At a time when much in the early Christian church had yet to be codified, St. Irenaeus wrote the book “Against Heresies,” and is credited with being the first to declare the Gospels of Matthew, Mark, Luke and John to be read by all Christians.

There are 36 declared doctors of the church. As doctors — think “teachers” —they are recognized for their significant contributions to theology or doctrine through their research, study and writing.

The first four doctors, declared in 1298, are St. Gregory the Great, St. Augustine, St. Ambrose and St. Jerome. The last three, all declared in this decade, are St. John of Avila and St. Hildegard of Bingen, both in 2012, and St. Gregory of Narek in 2015.

The other doctors of the church, listed in chronological order of when they were so declared, are: St. Thomas Aquinas, St. John Chrysostom, St. Basil the Great, St. Gregory of Nazianzus, St. Athanasius, St. Bonaventure, St. Anselm, St. Isidore of Seville, St. Peter Chrysologus, St. Leo the Great, St. Peter Damian, St. Bernard of Clairvaux, St. Hilary of Poitiers, St. Alphonsus Liguori, St. Francis de Sales, St. Cyril of Alexandria, St. Cyril of Jerusalem, St. John Damascene, St. Bede the Venerable, St. Ephrem, St. Peter Canisius, St. John of the Cross, St. Robert Bellarmine, St. Albertus Magnus, St. Anthony of Lisbon and Padua, St. Lawrence of Brindisi, St. Teresa of Avila, St. Catherine of Siena (Sts. Teresa and Catherine are the first two women declared doctors, both in 1970) and St. Therese of Lisieux.

Half of the doctors lived prior to the Latin-Orthodox schism of 1054, and they are generally regarded in high esteem by the Orthodox, although they do not use the phrase “doctor of the church.”

How does one become a doctor of the church?

“It typically begins with the originator of the cause for sainthood who has already done the extensive research and analysis required,” said a message from Bishop Rhoades. However, since St. Irenaeus was canonized before the schism — the Orthodox also consider him a saint — that does not apply here.

“If there is a desire to have the saint named a doctor of the church, the promoter of the cause must do further research and study and reach out to solicit broader consensus across nations that this would be a worthy pursuit,” Bishop Rhoades said. “The congregation has said that the support of entire episcopal conferences is very helpful in discerning these types of petitions.”

Msgr. Jeffrey N. Steenson, the retired head of the Personal Ordinariate of the Chair of St. Peter — established by Pope Benedict XVI for former Anglicans who have joined the Catholic Church -- waxed enthusiastic about St. Irenaeus’ virtues.

“He had a wonderful way of speaking about the nature of apostolic traditions,” Msgr. Steenson said, quoting one adage of St. Irenaeus: “Where the Holy Spirit is, there is the church. And where the church is, there is the Holy Spirit and all of its graces.”

He added, “St. Irenaeus again is an incredibly important patron and saint today in rebuilding the church of God,” calling him “the first systematic theologian of the church. “Literally, the first text that we have that speaks to the role of the Blessed Virgin Mary in the life of the church,” saying that the notion of Mary as mother of the church originated with him.

The request came to the U.S. bishops from Cardinal Philippe Barbarin of Lyon, France — the region where St. Irenaeus ministered — as the diocese is preparing a yearlong celebration of the saint in 2020. “The cardinal particularly sees Irenaeus’ teachings as speaking to our times when there seems to be a reemergence of gnostic ideas,” Bishop Rhoades said.

Cardinal Barbarin is appealing a six-month suspended sentence handed down earlier this year for failing to notify authorities of an abusive priest in his diocese.
