Anyway, every week, he gives the communion to the other people (saying the Body of Christ) , then for me he says nothing, offers me my host which is in a little vessel, and I just have to pick it up myself and take it. He doesn’t say anything to me. It feels weird and hurtful. Like he doesn’t believe it’s the Real Presence? And then this week, I get to the front, and although I knocked at the sacristy and greeted him as per request, he didn’t have a host for me, then sort of half offered me a normal host, so I felt awful basically rejecting Christ, then had to shuffle off back to me seat empty.
Although I do not suffer from the same level of sensitivity, I’ve experienced much the same in the past (although I have to say that, since ordination, it’s been less of a problem

). One time, we had a visiting priest and, although he was told about me and about the low-gluten host in a pyx on the altar, he didn’t quite seem to get it. So when I approached to receive communion he offered me a regular host, this is what followed:
Me: Pyx.
Priest: [looks at me blankly]
Me: “on the altar”
Priest: [offers me the (closed) pyx]
Me: No, give me the host in the pyx.
Of course all of this is accompanied by feelings of awkwardness as I stand there, holding up the line. On another occasion, I got sick of a priest just offering me the (admittedly open) pyx so, rather than accepting it I said to him “could you please take the host out of the pyx and give it to me”. those times when I couldn’t receive the host but only the chalice were also particularly tough - I’m of course aware that Christ is present equally in both species but there was still a sense of something missing.
Sadly, most priests in my experience don’t understand and so, the simple reality, is that you need to educate your priest(s) so that they understand on the one hand, that this isn’t just some trendy new-age lifestyle choice, but on the other, you’re not going to die if even one half of a nanogram of gluten should happen to come into contact with you! That said, at least the priest has taken the effort of acquiring low gluten hosts for you rather than you having to do it (and pay for them) yourself. If, for some reason, he can’t provide a low gluten host then he should at least make it possible for you to receive from the chalice - even it it means preparing another chalice. Ultimately, it’s the priest’s responsibility to ensure that you are able to access the Eucharist so put it on to him!
