Bill Drost

Disclaimer: I'm not asking this for the sake of Gossip or to slam an individual or an organization. I'm just curious.

A while back I read the book, "Bill Drost the Pentecost."
It is a biography of Bill Drost, an Apostolic missionary, and it is has a copyright date of 2000 by Word Aflame. It is a great book about a great man and what he did for God.

Today I was searching through a bunch of old Pentecostal Heralds and I found the following notice on page 7 of the July 1966 issue:

SPECIAL NOTICE
This is to advise that William
F. (Bill) Drost and his wife Ruth
have withdrawn their member-
ship from the United Pentecostal
Church. Because of this they are
no longer missionaries of this or-
ganization.
S.W. Chambers
General Secretary

Can anybody tell me what happened?
On pages 233 and 234 of the biography, that is about the time he left South America and went to Spain.
