Caller ID list the call as from "Back to God" which is a ministry of the Christian Reformed Church of North America, a small denomination with churches in the US and Canada.  They do have a radio ministry titled "Back to God".  HOWEVER the radio ministry web site list several phone numbers and this is NOT one of them. So this raises the question that the name might be spoofed by some scam operator.  They called to my dedicated fax line which answers on the first ring and they immediately hung up so I did not speak to anyone.
