Re: How should unconsecrated hosts be treated?
Your question reminds me of a story I once heard:
A priest was in his office at work one day when he heard a blood-curdling scream from the sacristy. Alarmed, he sprang up and rushed to the sacristy to see what had happened. The sacristan stood there with horror on her face and hosts scattered at her feet. "I accidentally dropped the box of hosts we just got in the mail from the religious-supply company," she stuttered. She was sure she had dropped our Lord himself, unaware apparently that he is not present when the hosts have not yet been consecrated.
In the same way, whichever one of you is worried about arranging the hosts in the ciborium should realize that there is no need to be so scrupulous about the care of unconsecrated hosts. While I don't recommend deliberately damaging them, as it would be wrong to damage another's property, you are certainly free to simply drop unconsecrated hosts into a ciborium rather than stacking them.
