Design Patterns of Catholic God
The Catholic faith, explained the way engineers think.
No biblical jargon. No Aristotle. No syllogisms. No culture-war rhetoric. Just clear software analogies that preserve the inner logic of Catholic doctrine without dumbing it down.
If you’ve spent time around technology, you can understand Catholic doctrine: from original sin through the Trinity to the Eucharist — in about 150 pages.

Why I wrote it
Catholic doctrine deserves to be presented in precise, science-aligned, contemporary language — and almost no one is doing it. As a software engineer, writing it felt like the most natural thing in the world.
— Karel Moulik, software engineer, practicing Catholic, and volunteer firefighter near Prague.
Who this book is for
Anyone who's spent time around technology and wants to understand Christianity precisely — whether you're a skeptic, a curious engineer, a lapsed Catholic, or a believer looking for a contemporary way to explain your faith to technical friends.
This book doesn’t proselytize and doesn’t tell you what to believe. It explains the system clearly. You decide.
What you’ll get
A compact thought model for reasoning about God, suffering, randomness, the identity of Jesus, and the sacraments — built from concepts you already use: design patterns, external randomness, words as fundamental building blocks, technical debt, and identity.
