"Isn't the Catholic Encyclopedia approved by the Church?"
It is a private publication. The very late Archbishop of New York allowed it to use the name Catholic.
Complaints should be sent to the estates of the editorial board:
Charles G. Herbermann, Professor of Latin and Librarian of the College of the City of New York
Edward A. Pace, then Professor of Philosophy in the Catholic University
Condé B. Pallen, Editor
Rt. Rev. Thomas J. Shahan, then Professor of Church History in the Catholic University
John J. Wynne, S.J., Editor of The Messenger
