My mission parish is very soon to be visited by our Bishop. I learned yesterday there is a custom to greet the Bishop with bread and salt. Can anyone say more about this? When does this take place - when he's first arriving, or some other time, like before the Liturgy he serves? Is there a specific greeting used? I'd ask a Priest, but we're currently awaiting assignment of a new Priest. I didn't turn much up with a google search either, so any info, advice, or links would be greatly appreciated. Thank you!
