You are arousing my suspicions. You haven’t actually answered my question, but instead replied with strange reminiscences. Do you think you could describe the circumstance without digression?
Did the Priest drop the host, then step on it? If so, did you see the follow up to this action? Nevertheless, you are right, there is no reason ever to step on the host-- unless that is, he was trying to prevent others from accidentally stepping on the host, who weren’t aware of what happened, and who may have had wet shoes, and there was no time to do anything other than step on the host for the time being, to prevent it from being kicked around or whatever else. IOW I can imagine a scenario, horrible as it is, that would not be sacrilegious or irreverent, where the priest may have done the only thing possible at that moment.
