THE BIBLE
Read in 10+ translations side by side: KJV, BSB, WEB, YLT, ASV, DRC, Vulgate, Geneva Bible, Tyndale, and more. Tap any verse to reveal:
• Interlinear Hebrew and Greek with Strong's lexicon definitions
• 340,000+ Treasury of Scripture Knowledge cross-references
• Commentary from Luther, Calvin, Chrysostom, Rashi, and Ramban
• The same verse in every other translation for instant comparison
THE COUNCIL
Ask Calvin, Luther, Aquinas, Chrysostom, and The Apologist real theological questions. Each scholar responds first with a real quote from each theologian — Calvin with precise Reformed logic, Luther with blunt conviction, Aquinas with Socratic precision. The Apologist (drawing from Lewis, Chesterton, Craig, and Keller) engages skeptics and objections head-on.

Premium subscription unlocks unlimited AI theologian conversations and THE LAW & GOSPEL SERMON ENGINE
Most AI tools generate generic outlines. Theologica's sermon engine is built around the Law & Gospel framework at the heart of Reformed and Lutheran preaching — the movement from conviction to grace, from human need to divine rescue.
Start from any saved passage. Build your outline. Then generate a full preachable sermon that follows the structure the Reformers themselves used: exposing the law's demand, then proclaiming the gospel's answer. Control tone, conviction level, and awe. Export for delivery or editing to make it your own.
