Canonist Ed Peters has an interesting column exploring an answer given to a question in the "God Squad" Q & A column . It’s worth a read because of what Ed has to clarify about the nature of the Eucharist and our reception of Communion, particularly since he brings the Eastern Churches into the picture in formulating the answer.
By the way, I really don’t know what this "God Squad" column is. The web site is sketchy and ad-laden and is not associated with the more famous "God Squad" of Rabbi Marc Gellman and Fr. Thomas Hartman. Doesn’t seem like a column that a newspaper would want to waste its time running, to me.
(update: See comments for more clarification, sort of.)
