Meri, Mary and the Mother of the Saviour by Stephen J. Bedard
And my response:
Those are good criticisms. D.M. Murdock responds to them, but you’d have to be the judge of how well she does.
The main point probably is that, by the Christian era, Isis was one of the most (if not the most) well known Egyptian deity, and one of the most widely worshipped in the Roman Empire. So, it’s possible that the term Meri was beginning to be identified with her. However, Isis (and Isis syncretizations) were referred with meri and similar terms all the way through the centuries prior to Rome being Christianized.
Even though the Egyptian term Meri could refer to even inanimate objects, I don’t know if there is any evidence that Jews and Romans would’ve been familiar with that meaning. It probably would’ve been most known as an epithet or, as Murdock argues, maybe even as a name. Very few non-Egyptians could tell an ipethet or a name apart when it was stated both as Isis-Meri and Meri-Isis. Murdock sees evidence that Meri was beginning to be used by itself.
As for the second problem, Mary isn’t used exclusively for either Egyptians or for Jews. Mary was a common name for Pagan goddesses. So, it isn’t surprising that it was a popular name for people as well. As for the 6 Marys of the NT, Murdock mentions this and hypothesizes a possible connection to 6 Hathors (as Hathor was the goddess of love that became identified with Isis).
All of this is is just one tiny aspect of the mythicist theory. It doesn’t stand or fall on one single detail. Meri is just a possible connection that many reputable scholars have written about. There are many other possible connections that mythicists point out. As the possible connections increase so does the probability of those connections.
