Apologetics Profile – Episode 327: Examining Catholic Mariology with Pastor Leonardo De Chirico – Part 1 (February 2, 2026)

Main Theme & Purpose

This episode delves into the doctrine of Mariology in Catholicism, with a focus on its historical development, theological significance, and the key points of divergence between Catholic and Evangelical Protestant beliefs. The hosts, James Walker and Daniel Ray, engage in an in-depth conversation with Pastor Leonardo De Chirico, an Evangelical Protestant pastor in Rome and author of "A Christian's Pocket Guide to Mary, Mother of God." The aim is to respectfully analyze the biblical and doctrinal underpinnings of Mariology, challenging its necessity and biblical basis from a Protestant point of view, while seeking to foster meaningful interfaith dialogue.

Key Discussion Points & Insights

Introduction to Mariology and Its Importance in Catholicism

• Mariology is not a peripheral issue but central to Catholic identity and doctrine.
• Four key tenets: Mary as Mother of God (Theotokos), perpetual virginity, immaculate conception, and bodily assumption.
• Acceptance of these Marian dogmas is non-negotiable for Catholics; disputes are considered heresy and may result in excommunication. (00:17–03:00)
• The term "Theotokos" (Mother of God) was confirmed by the Council of Ephesus (431 AD) to affirm Christ’s divinity and humanity. Both Protestants and Catholics agree on this Christological point, but differ on the implications for Marian veneration.

Protestant Critique of Marian Dogmas

Mother of God (Theotokos)

• Meant to defend Christ’s divinity more than to exalt Mary. Modern Catholic Mariology, however, has further elevated Mary beyond this original intent.
• “Theotokos...was never intended to exalt or venerate Mary to the extent of Catholic devotion to her as practiced today.” (~03:00)

Perpetual Virginity

• Catholicism teaches that Mary remained a virgin throughout her life; Protestants see biblical indications she had other children (Matt. 13:55; Mark 6:3).
• The Greek ‘adelphoi’ (brothers) is argued by Catholics to mean cousins, but Protestant scholarship contends there is no biblical precedent for this usage.
• Protestant reading suggests Mary and Joseph had normal marital relations after Jesus’s birth (cf. Matthew 1:25).
• “There is nothing in the Bible that unambiguously declares that Mary took a vow of chastity…” (~05:00–08:00)

Immaculate Conception

• Proclaimed as dogma only in 1854 by Pope Pius IX.
• Catholics cite Gabriel’s greeting, “full of grace” (Luke 1:28), as scriptural support; Protestants argue this is not substantial enough for such a doctrine.
• Pastor De Chirico: “To assume Mary has been sinless from birth is to assume egregiously far more than what the biblical texts actually tell us.” (~09:00–11:00)

Bodily Assumption

• This dogma was established in 1950 by Pope Pius XII.
• Raises theological questions about death and the consequences of sin—and whether Mary, presumably sinless, should have died at all.
• Lack of biblical or early historical basis for her assumption.

“Mariology Belongs to the DNA of Catholicism” (12:12)

• Pastor De Chirico: Emphasizes how Mariology is continually evolving and forms the core of Catholic faith, regardless of the Pope’s background.

  “Mariology lies at the core of the Catholic faith. It is not in the periphery...It belongs to the DNA.” (12:36)

• Even Popes less exposed to “folk religion” aspects strongly encourage Mariological devotion, indicating its deep integration into Catholicism.

Historical Development: Lex Orandi and Lex Credendi

• Council of Ephesus established Theotokos for Christological reasons. Over time, the devotional (lex orandi) and doctrinal (lex credendi) aspects of Mariology intertwined, leading to Marian devotions gaining theological legitimacy.
• “The people’s prayers and devotions to Mary began to reshape doctrine itself.” (15:55–23:00)
• Early creeds focused on Christ; references to Mary were later additions and eventually gateways for Marian dogmas to become central.

Theological and Scriptural Challenges

• Mary as the “Most Pure Creature”

  “She belongs to the creaturely realm...the most perfect creature...But...when it comes to devotional prayers and practices, in practice, they do break the line.” (24:53–27:03, De Chirico)

• Protestant critique of prayers to Mary: Acts of devotion risk infringing upon the boundaries between Creator and creature.

Popular Culture: The “Hail Mary” Pass

• Daniel Ray references the NFL’s famous “Hail Mary” play as an illustration of Marian devotion’s influence on culture, signifying entreating Mary’s intercession in desperate times. (27:04–27:58)

Intercessory Role of Mary

• Catholics distinguish between Christ as sole mediator and Mary as intercessor, but Protestants find no biblical foundation for this.

  “There is no place in Scripture that warrants us to have the need to believe that she was preserved from original sin…this is not an opinion, this is a dogma…like the Trinity.” (30:18–31:58, De Chirico)

Accretions in Marian Interpretation

• “Full of Grace” (Luke 1:28): De Chirico critiques how the Catholic tradition adds layers of interpretation not justified by the original Greek.

  “The angel tells Mary that she is [favored], she has received God’s grace…There is no special status, no eminent place that is given…” (36:15–39:10, De Chirico)

Mary as the New Eve

• John Paul II’s encyclical “Redemptoris Mater” (1987) used the analogy of Mary as the new Eve—a typology present in early Church Fathers but later became a full-blown theological doctrine in its own right.

  “The illustration became a theological point in and of itself...that speaks of the danger of Mariology becoming an idol or Mary becoming an idol…” (39:56–45:00, De Chirico)
