The low-low-gluten host made by the Benedictine Sisters does not affect your antibody levels - many celiacs have been taking these hosts on a weekly basis and have not had a rise in antibodies. The Sisters worked long and hard to come up with a host that meets the standard to be consecrated.
If you attend Mass you are not in mortal sin. Recieving communion is not required, although I personally think you are missing a lot of graces. Just recieve the blood. It is the whole Jesus, body, blood, soul and divintiy of our Lord Jesus Christ.
If you are receiving the regular Host, you are most definitely receiving too much gluten…Have you had your antibody levels tested recently? You can receive the low-low-gluten host with very little difficulty as I described - why would you take chances with your health?
Sorry, I should mention I am not a diagnosed celiac (although I suspect I could be, but cannot undergo diagnosis at this time)… so I classify myself as ‘gluten intolerant’ and continue receiving the regular Host because I want to & it does not cause me any adverse symptoms. It was unclear whether the original poster is celiac or gluten intolerant – and regardless, I’m not trying to give medical advice, just stating something that is currently working for me!
It’s a precept of the Church to receive the Eucharist at least once a year. Not doing this is a mortal sin, if you didn’t have a good reason. A person with a gluten intolerance should receive from the chalice only, or use gluten-free hosts (this really only works at a church where the priest knows you & understands your situation- they’d have to store gluten-free hosts and set one out for you whenever they see you at Mass, or you’d have to have them at home, and bring one for yourself whenever you come to Mass- just, please, be sure not to confuse people into thinking you stole a consecrated host- don’t keep them in a way that strangers can see you with them in the pews or outside of church).
