"A must have app for theology students."
-Fr. Thomas Guarino, Prof. of Theology, Seton Hall University

"An app that helps you go deeper in faith."
-Fr. Antonio Spadaro, S.J., Editor-In-Chief, La Civiltà Cattolica

"More than just questions and answers, and yet so concrete."
-Anne Carpenter, Asst. Prof. of Theology, St. Mary's University

"Comprehensive and easy to navigate, this app is helpful to my
students and is a valuable one-stop reference in my own work."
-Christian Cintron, Adj. Prof. of Religion, Fairfield University


Theologica is the simple, yet comprehensive theological study app for the iPhone. Drawing from the rich treasures of the intellectual tradition of the Church, from the 1st to the 21st century, this app is designed to be an essential study tool for both students and teachers of theology as well as for anyone who desires to “think faith”.

Theologica features 5 tabs: Overview, Reference, Dictionary, Maps, and Explorations, which enable its users to enhance their knowledge of theology in multiple contexts.


The Overview tab presents a wide-angle view of theology as a dialectical enterprise that continuously seeks to better understand the Faith of the Church in a given historical situation. To fulfill that vocation, theology draws on various sources in order to faithfully interpret the signs of the times. The primary sources are: Magisterium, Sacred Scripture, Church Fathers, Ecumenical Councils, Creeds, and Liturgy. All of these sources, though distinct, are organically related to the life of the Church. Theology is always practiced in a particular historical and cultural context. Thus, cultural trends and indicators of the worldview of modern men and women necessarily affect the way in which the Faith of the Church is understood. It is therefore vital for theology to pay attention to these signs in order to fulfill its vocation. They include: Philosophy, Science, Technology, Politics, Economics, and the Arts. While not exhaustive, these aspects of life in the 21st century are the primary factors which affect the thinking of people everywhere.


The Reference tab features a curated list of live links for each category in the Overview tab along with those sites that feature theology in action. Most of these sites contain significant documents which are referenced in the Dictionary.


The Dictionary tab includes a list of over 500 of the most commonly used theological terms in both high school and college classrooms, grouped by the categories: Systematic, Historical, Moral, Biblical, Liturgical, and Cultural. Terms can be bookmarked for quick access when used for exam preparation. Definitions contain extensive links to curated resources for further reference, publicly available online.


The Maps tab includes over 40 custom pin locations grouped by the categories: Old Testament, New Testament, Church History, and Social Justice. Each location includes a detail page with additional information on the given site as well as links for more information. Theology is practiced in ancient, historical, and modern geographical contexts, and this is clearly expressed in Maps.


The Explorations tab features in-depth analysis of specific questions in theology, which are generated by the dialectic it has with modern culture. This tab also includes periodic interviews with contemporary theologians and other cultural influencers who are actively engaged in shaping the various contexts of theology. This tab features various such explorations on a regular basis.

Theologica began as an idea for an iPhone app that could serve as a comprehensive study aid for students as well as an instructional tool for teachers. It is and will remain ad-free with no additional fees for future updates.

What's New in Version 1.0.5

Version 1.0.5 brings more terms for biblical studies and systematics in the Dictionary tab, new map pins in the Maps tab, and a new exploration of Genesis chapters 1-3, 6-9, and 11 through the lens of the Documentary Hypothesis.

Theologica continues to increase its database, making it ever-more useful for students, teachers, and all users to better learn theology.

Future updates will feature additional presentations, interviews, links, terms, map pins, and improvements to the user experience.

Thank you for your support of Theologica, the only theological study-app for the iPhone.

"The recent discoveries and findings of science, history, and philosophy raise new questions which affect life and which demand new theological investigations." - Vatican II, Gaudium et Spes, 62.
