Is the book of the urantia and the book of the apocrypha true?

The "book of the urantia" has also been expressed as the "Book of Urantia", but neither expression is the published title (since first publication in 1955): the Urantia Book.

The "book of the apocrypha", at least in association with the Urantia Book, is not a published book and refers more to the loose collection of writings and notes (a collection not necessarily identified in its entirety) created during the reception of the Urantia Papers in the early 20th century and their later compilation into the Urantia Book.

Incidentally, "apocrypha" often refers to secret or hidden writings, so how would such writings be evaluated by most truth seekers?

Whether or not such a Urantia apocrypha has value - relative to the purpose and message of this revelation - might be determined in later decades. For the interim, this apocrypha is only assumed to exist as a formal collection, is mostly controversial, and is usually ignored by long-time students of the Papers.

Since the entirety of the apocrypha still needs to be identified, ascertaining its truth is the challenge for later generations. As for the Book, which reveals our planet's existence amongst many other inhabited planets in an intelligent, spiritual universe of unfathomable size, its message of the brotherhood of man and fatherhood of a universal creator is key - if this is believed to be true, one can easily find truth in the Papers.

The ForeWord page of the online Urantia Blessing site identifies Acknowledgments by the authors/sponsors of the Papers and lists those authors/sponsors by their universe title. The Acknowledgements provide a good starting point for determining whether or not an epochal revelation (the fifth to our planet) has been received.
