From a reader…
QUAERITUR:
Would changing the shape of a host be allowed in order to decrease the chance of the priest touching a communicant’s tongue? Would an oval shaped host, for example, make it easier for the priest when distributing the Eucharist to a communicant who isn’t very good at receiving on the tongue? I think receiving on the tongue will be limited if not banned once Mass is public again and just thinking if the host has to be round and if a different shape could be helpful. Sorry if this is a dumb question.
