Consequently, just as any group engaged in the same enterprise develops its own jargon, Catholic teaching has developed a vocabulary which may seem opaque or arbitrary to those who left the conversation almost half a thousand years ago.

But it seems co-redeemer was a fairly modern fabrication...

Redeemer is an English word...Co is also an English word...So we know what co-redeemer means...If you guys want to say that co is a Latin word, you should use the Latin word for Redeemer to avoid obvious confusion, or delusion...

I wouldn't want to guess how many Catholics who don't study the bible, who don't know a lick of Latin go away from your Masses hearing Mary, co-redeeme rand actually thinking Mary is an equal redeemer along with Jesus??? I'll bet the number is staggering...

Well co-redemptrix is Latin. Redemptor, masc.; redemptrix, fem.

I don't know the history of the idea.

In 17 years as a Catholic I have not heard the topic come up once in a sermon, and certainly not in a Mass.
