I was in the Communion line at a very hoity-toity Latin Mass once when a guy in front of me reaches out his hand and whacks they kid in front of him because he didn't apppend himself to the far end of the kneeling line...
Loving correction. And yet we sin sometimes in delivering it without thinking it through.
Nothing wrong with learning the why and why not of Mass - that’s how we learn to love even ever more about it and our relationship with Jesus.
Praised Be Jesus Christ!
