MiserereMeiDei and maryjk, that’s good to know, and yes I forgot to include that I do receive on the tongue.
Tis_Bearself, thank you for the reply. I had briefly given thought to the possible risk of the Chalice spilling - it’s a bit awkward because the lay member is standing on a step and so it would involve them having to bend and reach down, whilst I would be reaching up. Also, parishioners who choose not to receive the Blood of Christ would be passing by behind me; I personally think that if I were kneeling, there would be enough space between my legs and feet and the front pew for people to walk by, but it could still be a hazard I suppose. I’ll mention the issue to my Priest as you suggested.
