Each year of Exodus 90 thus far we have taken feedback from participants to improve the experience for the future. Today's version of the Exodus 90 Spiritual Exercise is the fruit of a living fraternity.

If so, then yes you will want to get the new book or you and your fraternity brothers will be quite disconnected. Some days you won't even have the same scripture, especially towards the end.

The entire Exodus 90 Spiritual Exercise was re-written by author and director of mission, Nathaniel Binversie, and released for the first time in January 2019. All ninety reflections were re-written to be cleaner, more relatable to lay men, and flow from day one to day ninety in a more unified way.

In addition the prologue of the exercise, now referred to as the Field Guide, was completely rethought and reworked with heavy support from Sacred Scripture and the Catechism of the Catholic Church.

Overall much of the exercise will still feel quite similar to the original text in thematic. Though, many of the reflections will be quite different or even completely different than what was originally there. This is especially true for Days 30-90.

The scripture translation used was also replaced. Now the RSV-2CE has been inserted for all the days reflections, a more accurate and easier to read translation of the bible from what was used before.

If you have this version you may consider getting the latest version of Exodus 90.

In the later portion of 2019 a group of priests and theologians reviewed the Exodus 90 Spiritual Exercise and a few further changes were made to clean up the language, fix any errors, and make commentary an preparation more accurate and more helpful to men taking up this exercise.

In January of 2020, the latest, and final major-change version of the exercise has been released. This version has been granted both a Nihil Obstat and Imprimatur from the Diocese of Fort Wayne-South Bend, the home diocese of Exodus Inc.

If you have this book, you have the latest major version of Exodus 90. Any further versions would only contain minor grammar or spelling changes, if any are to be found in this version.
