Why hold hands just for the Pater Noster and not for the Collect or the Agnus Dei? It’s notable for being the only congregational prayer in the Ordinary that has the priest with outstretched arms. It also seems to be a near-universal custom for the people holding hands to then raise them during the doxology.
It seems plainly obvious to me that the point of holding hands at this part of the Holy Mass is because it mimics the priest’s gestures. Same goes for holding your hands up when you respond “and with your spirit”.
I’m only speculating (which is what you are are doing), but I think that perhaps the reason for the hand-holding during the Lord’s Prayer is that it is a prayer that Protestants and Catholics both know, so the gesture is a symbol of the peace and love between these two groups of Christians.
When Protestants are in attendance at Mass, this is the ONE part of the Mass that they recognize and can participate in (except that many tend to add the “For Thine is the Power, the Glory, and the Power” immediately after the prayer, instead of waiting for the priest.)
The other prayers you mention–the “Collect” and the “Agnus Dei” are not done in many Protestant churches, and so Protestants are left out and stand there not knowing what’s going on.
I know that some Catholics think, “So big deal–why cater to Protestants in the Mass? The Mass is about Jesus, not Protestants!”
Well, speaking as an ex-Protestant, I’m grateful for any effort by Catholics to reach out to me and my family! It worked.
One more thing–in many of the Pentecostal churches, raising the hands during prayer is the normal thing to do. Everyone does it. It’s Biblical–I Timothy 2:8 is a beautiful verse "Therefore, I want the men in every place to pray, lifting up holy hands, without wrath and dissension. "
They certainly aren’t trying to emulate a Catholic priest.
Funny how a gesture that is supposed to eliminate wrath and dissension (according to the Bible) actually causes it.
