As a general principle, you should not do things that are NOT specified as part of a liturgical rite. Now, people can do private devotional things like beating their breast at the lamb of God or quietly saying little prayers to themselves at the elevation of the host, etc. … but gestures and actions that are done by the entire assembly… when they are not part of the rite is something different. The rubrics also do not say anywhere that we can’t all give each other “high fives” at the conclusion of the Gospel proclamation… that does not mean we can do it just because we are not explicity told not to. However, a “high 5” does not symbolize unity, but holding hands does. Your example brings in a non-religious movement to try and compare to a posture that does have some religious connection - we say “our father”, not “my father”; “give us”, not “give me”. While there may be good, solid liturgical reasons that holding hands may not be preferrable, there are also some intelligible connections between holding hands and a group prayer.
Further, because you like the symbolism of beating your breast but do not like the symbolism of holding hands, you find it ok to do one but not the other on the basis that"everyone" is doing the hand holding, but only “individuals” are doing the other. That is falt out cafeteria GIRM allowances.
AngelicDoctor;1914129:
I have heard (not positive) that the hand holding was a fad that Catholics in America started by imitating some Protestant churches.
And the point is? So what? St Patrick saw the Druids using a fire to celebrate the coming of Spring, so he started a fire on a different hill, to celebrate the ressurection of Christ. And that wasn’g from Protestants… anyone who knows much of Church history will know that the Church has adopted any number of symbols and actions throughout history from non-Catholics, including heathens. and so if it was adopted from Protestants, so what? They believe in Christ too. Or didn’t anyone let you in on that little secret?
Frankly, I don’t care if people hold hands, or don’t, or use the orans posture; what I care about is that they say the Our Father fervently. And I suspect that if we all said it fervently and paid a little less attention to the hands issue, the issue would become a non-issue.
