9. Holding hands at the Our Father
First off, this looks like it was born out of necessity by people standing next to one another in the Orans position, right? The people at the end of the chain have their un-held hand raised, do they not? Expecting or obliging the whole community to join hands is unacceptable because it has not been approved, but even small groups doing it is problematic and dissonant. It also emphasizes a horizontal perspective at a moment when we ought to be focused on the vertical. And it distracts from the true act of union, the reception of Holy Communion.
Informative and good. Congratulations for the various articles/prayers. God bless.
