as Catholics (adding error to error) believe Christ gave His actual flesh and blood to be eaten, so it is emphasized that Mary gave Him this, being fashioned out of Mary's pure blood and even being “kneaded with the admixture of her virginal milk,” so that she can say, "Come and eat my bread, drink the wine I have prepared" (Prov. 9:5); I have never heard that before.
My first inclination was to say *You CANNOT possibly be serious*, but I know you too well and know that you have it backed up.
How can otherwise intelligent people fall for such fantasies (or drivel - take your pick)?
