We were taught in grade school (mid sixties) to hold our hands together in the traditional manner while praying. Palms together, fingers extended, pointed upward towards heaven. We were also taught to bow our heads slightly.
That is how I do it today as well. I find it keeps me focused on God, as well as assuring I pray the prayer with sincerity and reverence. I’ve noticed that many who hold hands during the Our Father, also tend to tilt their heads upwards. This is the opposite of how I was taught.
After the “For the Kingdom, the Power…”, I keep my hands in this position to maintain my awareness that another very important prayer is about to be said following the sign of peace.
I find it very hard to turn my focus away from my standing in the presence of God , to focusing on my neighbor, and then just as abruptly, immediately praying the Agnus Dei.
So, for the sign of peace, I simply look first to the person beside me in the pew. If they turn my way, I’ll say God bless you brother/sister, and offer a smile and nod. If anyone else in my pew looks my way, I’ll smile and nod. Once those in my pew have been acknowledged, I’ll return my focus on the Altar Crucifix, unless someone in the pew in front of me is turned my way. If not, I’ll close my eyes and bow for the Agnus Dei.
The only time I’ll turn to the pew behind me, is when I’m at a weekday Mass, and no one else is in my pew or the one directly in front of me.
If someone offers to shake hands during the sign of peace, I simply separate my hands slightly from the prayer position, turn a palm toward them, smile and nod. The majority of the time, they return the smile, seemingly ok with that. The only exception I will make, is if a small child offer his/her hand as a sign of peace. If a small child is learning to follow the Mass, I’ll not confuse them by rejecting their offer of kindness in a manner they may not understand. Kids emotions are fragile.
To those who have no problem with holding hands and shaking hands during Mass, I have no problem with them doing so. I don’t believe God is offended either.
