Christ is in our midst!!
only allowing for the Eucharist under one species, and in the hand
I suspect that what you are seeing in Byzantine Catholic parishes--if this is truly the present case--is a modification of traditional practice in response to the Covid pandemic. I would not take such practices as being any kind of norm. We have had discussions about parishes in the United States modifying their practices in response to the pandemic, as well as some of our Orthodox brethren describing modifications to their practice. We have a dangerous virus loose and the practice of putting a single spoon into everyone's mouth has brought serious questions and reflection about Byzantine practice both in the Byzantine Catholic and Orthodox Churches. A temporary measure should not be something that puts you off. The alternative might be suspending the distribution of the Mysteries--a measure no one wants or would even consider.
