Commission of Ecumenical Translators/XD

The Commission of Ecumenical Translators or C.E.T. was a convocation that occurred on a neutral island of Old Earth (implied to be the Hawaiian islands) in 25 BG.

Encouraged by the Spacing Guild and the Bene Gesserit, the leaders of all the religions of the known universe, every faith with more than a million followers, had a representative meet "in the common belief that there exists a Divine Essence in the universe."

At the end of seven standard years of controversy and paradox that spawned much violence and nearly led to chaos, the C.E.T. finally completed the Orange Catholic Bible, the Liturgical Manual and the Commentaries. At this same time, the Azhar Book was assembled, and the Litany Against Fear was composed likely by the Bene Gesserit.

Discrepancy
In the timeline at the end of Hunters of Dune, it is said that it had occurred in the 1st century AG. However Sisterhood of Dune would later contradict this, placing it at 25 BG.
