"The chalice of benediction which we bless, is it not the communion of the blood of Christ? And the bread which we break, is it not the partaking of the body of the Lord? For we, being many, are one bread, one body: all that partake of one bread." (1 Cor 10:16-17)
Astounding that an Evangelical would convert because of Mary. Quite interesting too that the convert, John Weidner, correlates this with the sacraments. Not that it's shocking -- it makes sense, after all.
