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.

Richard Carrier’s Pocket Guide to Mythicism

It’s a good start.

I would like to like this app more than I do. Hopefully, future updates will add some of the features that I think are missing. Firstly, the app is designed with only mobile phones in mind. On an iPad, it only appears in portrait orientation as if the tablet were big iPhone. Although its layout and workflow are logical and efficient, most of the entries only scratch the surface of the topics they are related to. The app would benefit greatly from hypertext links to Dr. Carrier’s blog, Wikipedia, and/or other Internet sources. It is also sorely in need of a search function.

luke lies, paralleling the roads... not scrolling
copying genesis , copying moses in exodus not scrolling
getting late stopped at responses to arguments for historicity

Ironically the only sources cited in this app are Bible passages. Contains what seems like baseless conjecture and I expected much more from something attempting to go against millennia of academia.

Interesting discussion points but not what is advertised.
