text: Your concerns are noted, John, and vey understandable.  This is a good time to educated parish pastors and local bishops around what celiac disease is and the serious consequences for some if the recommendations of the Congregation for Divine Worship are rigidly followed.  Most folks do not know much about it.  May I suggest that you write a letter to your bishop with a copy to your pastor about it?  At the same time, it is more than useful to note that one can receive the Eucharist via wine only.  I sometimes do so when at a parish for a Sunday mass and the lines are too large for reception of the host.  Thanks for our helpful comments!
