CHRESTUS is a revolutionary tool for investigating every argument for and against the historical existence of Jesus. This app contains a reference glossary, a Bayesian calculator, in-depth articles on minimal mythicism, a chronology of early Christianity, and a list of both people on both sides of the discussion.

The Bayesian calculator allows you to estimate the probability that Jesus existed with whatever evidence you chose to include. Bayesian analysis uses a basic model widely employed by scientists, governments, corporations, and even historians. Bayesian analysis is the best way to weigh the evidence for or against any claim you encounter.

The chronology graphic allows you to visually see the references to Jesus and when they happened. This is a very important factor in historical studies. This app addresses all known arguments both for an against the historical Jesus and allows you to determine whether Jesus actually existed.

This app was developed in collaboration with Dr. Richard Carrier (author of On the Historicity of Jesus) so all information in CHRESTUS is based on the most recent scholarship in the field of historical Jesus studies.

Continuous updates to the application makes it the most up to date compendium of information on the historicity of Jesus.
