Introduction

Compendius Maximus is a companion to the Catechismus Maximus, developed by Ask A Christian using advanced AI tools to expand 200 concise theological answers into detailed, logically cohesive arguments. Each answer, originally packed into a few paragraphs, is unpacked here to reveal the full depth of its theological reasoning, progressing from premise to conclusion. This work bridges the gap between new believers and seasoned scholars, offering clarity for those exploring Christianity and rigor for advanced study.

Compendius Maximus is a living document under active development. We thank you for your patience as we build this massive undertaking and invite you to explore available content and check back for updates. To fully engage with this compendium, start with the Catechismus Maximus, which provides the foundational Q&A format that this work expands.

At its core, this project reflects the simple gospel from a first-century, Protestant, non-denominational Christian perspective (aka Biblical Christianity, *wink*): God, the Creator, sent His Son, Jesus, who lived a perfect life, died for our sins by the shedding of His blood (Matthew 26:28, Hebrews 9:22), and rose again, offering forgiveness and eternal life to all who repent and believe (Romans 10:9–10). As Ask A Christian humbly reminds us: “The gospel is like a lake—new believers can wade in without fear of drowning, immediately grasping the most important truth: Jesus’ death, burial, and resurrection for the forgiveness of sins through faith. While scholars can dive down and never reach its depths.” This compendium invites you to grow in understanding, knowing that the simple gospel is the foundation (John 3:16, Ephesians 2:8–9).

For new believers, this initial step secures eternal life and salvation through trust in Jesus, the prize won at the start. As Paul encourages, we move from the “milk” to the “meat” of the Word (1 Corinthians 3:2), deepening our faith while resting in that foundational truth.

This project was born to encourage those with great knowledge to remain humble in their pursuit of truth and to gently guide new believers, showing that the gospel’s simplicity is accessible to all.
