Recorded at the Nicaea Conference in Istanbul, this episode of The Westminster Podcast features a wide-ranging and incisive conversation with Pastor Leo de Chirico, a Reformed Baptist pastor serving in Rome, Italy. Drawing on his unique experience and years of evangelistic and theological engagement in a Roman Catholic context, Leo reflects on the significance of the Council of Nicaea, the purpose of the Nicene Creed, and what it really meant to confess Christ’s divinity in the face of Arianism. Rather than treating the creed as a sentimental or purely ecumenical touchstone, Leo argues that Nicaea functioned as an exegetical workshop—a Scripture-driven response to heresy grounded in the authority of the Bible.

From there, the conversation explores how different Christian traditions interpret the same creedal language within very different theological frameworks. Leo traces the divergent trajectories of Eastern Orthodoxy, Roman Catholicism, and Protestantism, contending that the Reformation did not reject Nicene Christianity but sought to recover what Nicaea assumed: the supremacy of Scripture as the norma normans. The discussion also turns to contemporary issues, including the renewed attraction of Roman Catholicism among evangelicals, the legacy of Vatican II, and the challenge of engaging a Catholicism that is adaptive, plural, and often misunderstood. Throughout, Leo presses a consistent theme: Christians may use the same words, but they often inhabit very different worlds—and faithful dialogue requires clarity, historical awareness, and a renewed confidence in Scripture alone.
