A Catholic Typological Series
Tracing the Arcs of Scripture from Figure to Fulfillment
Sturm & Róisín Publishing · Fírinne Imprint
Shadows and Substance is a complete eight-volume series that traces the major images, persons, events, and institutions of the Old Testament forward through every major reference point in Scripture to their ultimate realization in Christ, the sacraments, and the life of the Church.
The title comes from the language of Hebrews, where the old covenant is described as a shadow of the things to come, and the substance belongs to Christ. Every chapter follows a single arc — the Lamb, the Temple, the Shepherd, the Bride — from its first appearance in Genesis through its fulfillment in the New Testament and beyond.
The series is written from within the Roman Catholic interpretive tradition, drawing deeply on the Church Fathers and the four senses of Scripture: literal, allegorical, moral, and anagogical. Commentary from the Fathers — Irenaeus, Augustine, Chrysostom, Cyril, Ambrose, Ephrem the Syrian, and many others — is woven throughout the prose, not relegated to footnotes.
The series grew out of a conviction that most Catholics never learn to read Scripture the way the Church Fathers read it — as a single, unified story where every figure casts a shadow forward and every fulfillment reaches back. Typology isn't a scholarly technique reserved for academics. It's the native reading of the Church from the apostles forward, and it belongs in the hands of ordinary believers.
Each chapter is written to be read independently, without a teacher in the room. The prose is authoritative but not academic — a knowledgeable Catholic author walking the reader through the evidence, honest about epistemological difficulties, and non-combative toward Protestant readers. The goal is understanding, not conversion.
Believers who want to see how the whole of Scripture holds together — and how the Mass, the sacraments, and the Marian doctrines are rooted in the biblical text, not added to it.
Each chapter works as a standalone session. Companion study guides with discussion questions, reading assignments, and timing notes are in development.
For those entering the Church or recently received — a guided walk through the scriptural foundations underneath Catholic teaching, built from the ground up.
Written with Protestant objections in mind and addressed without hostility. The appendixes tackle the hard questions directly — Sola Scriptura, the Real Presence, the Marian doctrines, justification.
Every chapter is built on the Catholic tradition of reading Scripture through four complementary lenses — the same method the Fathers used, formalized in the medieval period, and reaffirmed in the Catechism today.
Twenty-two companion pieces that go deeper — bridge work spanning the whole series and topical deep dives tied to individual volumes. The series appendixes address the foundational questions a thoughtful reader will bring: How do Catholics read Scripture? What is the Church's authority? Why the Marian doctrines?
The main series anchors a broader shelf of related works, each designed for a different reader or setting.
Lesson plans with discussion questions, reading assignments, prayers, and timing notes — designed for small groups working through the series together.
Illustrated children's versions of select arcs — the Lamb, the Shepherd, Light, Water, Bread, the Garden, the Dragon, and the Ark of the Covenant — with age-appropriate language and a narrative focus.
A companion series adapting the typological content for Protestant readers — same arcs, reframed within the interpretive tradition that Protestant readers share. 57 chapters.
Scripture throughout is the Revised Standard Version, Catholic Edition. The Church Fathers and Doctors of the Church — from Irenaeus and Justin Martyr through Thomas Aquinas and John of Damascus — are public domain sources woven directly into the prose. Magisterial references draw on the Catechism, conciliar documents, and papal encyclicals where they illuminate the topic.
No modern theologians' published works are incorporated. Where a modern figure contributes a specific insight — Newman on development of doctrine, for example — the attribution is woven naturally into the prose.
