WHO CARES about the sign of peace?
The BODY, BLOOD, SOUL and DIVINITY of our Lord, Jesus Christ, is what is crucial!
It's part of the lex orandi/lex credendi thing. How we worship God (or don't as the case may be) is important. I can barely remember the sign of peace it's been so long since I attended a New Mass but I do remember it being very jarring and disorienting.
So no issue of liturgical compliance has any importance whatsoever? Each priest and parish is free to experiment, innovate, 'progress'? Why not just serve the Hosts in a drive-though? You're protestant not Catholic.
