Monsignor Pope Ping!
I would like it very much if we were to get a firm instruction at some point that we should shake hands with 3 persons max., and say only "Peace" or "The peace of Christ be with you."
This is not a signal for "fellowship time" or "meet & greet". It should take seconds, total. There are many, many times when a person can be --- should be --- all jovial, but this is not one of them. This should be solemn. Think of where it is: before the Lamb of God!
Just prior to the Agnus Dei, the optional (though seldom omitted) sign of peace is sung or said. Unfortunately, there are often excesses in what ought to be a modest greeting to those immediately nearby.
...
Don’t get me started on that do-called Sign of Peace. I can’t help but think that some malevolent force was involved in the placement of that interruption at such a sacred moment.
If it is so important for me to greet my fellow congregants it should be done at the beginning of Mass.
I do a quick giant waves of peace to everyone so I can be at peace with others and myself. This helps me to be at peace with God before holy communion.
