"Interestingly enough, during the Vatican Council there was criticism from WCC Circles of this Catholic willingness to extend the word and even the concept ecumenical to relations with non-Christian religions.

"Higgins claimed to reveal the existence of an ancient universal religion (he called it Pandeism), out of which all religious doctrines originated—a religion that yet survives as a secret, fragmented sect that carries its ancient messages in parts of Greece, the Middle East, and India, with its origins in the last."

"Regarding Western Pantheism, some people feel that the word "pantheism" is misused. Since theology is the study of religion and and means "all," pantheism implies following all religions.
