Am I missing something?
Someone posted a picture of a person holding up a Rosary in church.
It is probably during a Mass, although I can’t tell from that picture. For all we know, maybe it’s during a Protestant (Pentecostal) worship service, and the Christian in the picture prays what Protestants call the “Ecumenical Rosary.” (That’s how my husband got started learning about the Marian Rosary.)
What’s wrong with that?
I know lots of people, especially elderly people, who hold their Rosaries throughout Mass. I think it’s a comfort thing, or perhaps something that reminds them that they should be in an attitude of prayer throughout Mass. My husband will often start praying a Rosary before Mass, and then finish the Rosary after Mass, and he keeps the Rosary in his hands throughout the Mass.
My husband made several of my Rosaries, and I think that if (when) he dies (before me?

), I would probably find a great deal of comfort in holding onto his Rosaries during Holy Mass.
Why are we ascribing evil to this picture? Some people hold their car keys or the purse throughout Mass.
The picture is supposed to be from the OF during the Our Father where everyone is holding out their hands. Someone has a rosary in their hands.
There was a recent thread where a poster claimed that back in the old days everyone prayed the rosary because they couldn’t understand the Latin in the Tridentine Mass.
The picture, I am sure, was posted to show that even in the OF some pray the rosary.
