These communion hosts have an extremely low wheat and gluten content (less than 0.01% gluten), so they meet the requirements of strict churches, especially the Catholic Church which requires wheat+water only.
A friend suggested that carrying them in a pyx to prevent cross-contamination. However, there is <0.01% gluten in the hosts. So, really, this would be to prevent further cross-contamination.
Just to be clear, those with Celiac or those who are super sensitive to wheat or gluten might still have issues with these hosts. If that’s you, you might talk with your pastor about receiving a small amount of the wine from a designated chalice (no cross-contamination).
Either way, it’s a good idea to talk with your doctor about whether or not these altar breads are an option for you, medically.
