That is double talk. The Roman Catholic Church is doing everything it can to make those titles dogmatic. And there are many RC's who believe they are now. This forum is a case in point...there have been a large number of threads on those very topics, as well as others that elevate Mary far above anything justified by Scripture.
Co-redemptrix is a problematic title, even in Catholic circles. The above statement alone proves that it isn't worth my time debating you on the issue of veneration of Mary. Besides, it's quarter past midnight where I am. Time to go to bed. Good night, God bless.
