How did the cult of Iseum Campestre influence later Roman religions?

Celibacy is a practice that can be traced back to ancient pre-Christian religions. The priests of certain deities were required to be totally devoted to their religious roles; no interest in sex or in any mortal human being could come between them and their gods. This was especially true for the priests of female deities such as the Egyptian Great Mother Isis. A priest stood apart from other believers and mediated between them and the deity.
