What is on this site, where to find it, and the only place worth beginning.
If you are reading this, something brought you here.
Maybe someone invited you. Maybe you have been sitting with questions about your faith for a while and finally decided it was time to look for answers. Maybe you grew up in the Church and want to understand it beyond what you learned as a kid. Whatever brought you, welcome.
CRUX is not a podcast you listen to while commuting. It is not a two-minute devotional that makes you feel good before you forget it. It is a structured faith formation tool built for people who want to understand what they believe, and why, at a level that actually requires something from them. The modules ask real questions. The Bible studies require a Bible in your hand. There are things worth sitting with before you move on.
Start where you are. Bring whatever you have. That is the only requirement.
Whether you are approaching this for the first time or are a cradle Catholic who wants to understand what you actually believe, The Foundation is where to begin. Each module is split into two parts. Work through them in order — they build on each other.
The Five Pillars is 18 modules across five areas of Catholic teaching. It serves grades 3 through 8 at Beginner level and goes well beyond what most adults covered in CCD at Theologian level. Use the toggle inside each module to choose your depth.
Every module has two depth levels. Beginner gives you the essentials — the doctrine, the why behind it, and what it means for your life. Switch to Theologian for the fuller version: deeper Scripture, more historical context, harder questions taken seriously. Most adults who completed The Foundation are ready for Theologian level.
The Foundation gives you the framework. Bible Study puts Scripture directly in your hands. Once you have worked through the first few Foundation modules, add a Bible Study track alongside your formation work. The two are designed to complement each other.
Each study works verse by verse through a book of Scripture. There are reflection questions, word studies, and prompts built for both people new to the Bible and those who already have a foundation in it. A physical Bible is required — not just this site.

The Library is for people who have worked through the modules and studies and want to go further on their own. It includes books written by the creator of CRUX and a curated reading list from theologians and authors who have done the hard work of making the faith accessible at every level.
CRUX is a tool, not the whole toolbox. The modules and Bible studies on this site are only as useful as the preparation you bring to them. You will need a Bible, something to write with, and a place to record what you are learning. These are the three tools worth having before you begin.
The translation and commentary used as the reference text for the CRUX modules. It includes introductions to every book of the Bible, extensive footnotes, and reading guides that give you the historical and theological context you need. If you are starting your Bible library, start here.
Bible paper is thin. Most standard highlighters and ballpoint pens will bleed straight through it. The Mr. Pen Bible Journaling Kit is a set of non-bleed pens and highlighters made specifically for this. Worth having before your first study session so you are not ruining pages.
Every module on this site includes reflection questions and journal prompts. Writing your answers down — even roughly, even just a few sentences — does something that reading alone cannot. Keep a dedicated notebook for your CRUX work, separate from everything else in your life. You will want to look back at it.
