What if Christianity is not primarily a moral code, a private belief system, or a set of religious customs, but a way of seeing reality?
In this episode, Dr. Zachary Porcu joins the podcast to discuss his book Journey to Reality: Sacramental Life in a Secular Age. The conversation begins with the origin of the book, which grew out of Zac’s work teaching theology to students who often knew the basic claims of Christianity but lacked the worldview that made those claims intelligible.
From there, we move into the deeper question: what is Christianity? Zac argues that “religion” may not be the most useful starting point. Christianity is better understood as a worldview, a way of answering the question, “What is the nature of reality?”
That question leads into one of the central concepts of the conversation: the arche. Zac uses the term to move beyond the flattened modern image of God as a distant old man in the sky. Instead, he describes God as the source of being itself, the one in whom all things live, move, and have their being.
The conversation then turns to the Incarnation, the claim that the source of being, life, and truth became man in Jesus Christ. Zac explains why that claim was shocking both to Jews and Greeks, and why it remains revolutionary today.
We also discuss the difference between modern Christianity as intellectual assent and ancient Christianity as sacramental participation. To become Christian is not merely to agree with Christian propositions. It is to be grafted into Christ through baptism, Eucharist, and the mysteries of the Church.
Later in the episode, we discuss the Reformation, the rise of the secular nation-state, the older idea of symphonia between church and empire, and the myth that public life can ever be religiously or metaphysically neutral.
This conversation was recorded near the beginning of my Orthodox life. In that sense, it captures not a finished statement, but a beginning: the attempt to understand a world that once was, and still is, even if many of us have forgotten how to see it.
