I don’t know how old you are; I m an early baby boomer (you do the math). I have seen a lot of change in the church in those years. I have never, and I mean never, seen any change that was done “for the sake of change”. Having said that, I do not go around demanding that someone tell me why they changed it; to me, that implies an attitude that they have a duty to me. IMHO, they don’t have the duty; I do.
For all I know, they wanted you, and I, and everyone else who received ashes, to get out of a complacent attitude of constant repetition, and “wake up”. In other words, it may have been that the formula, which is not and never was cast in stone, was seen as not sending the essential message of the Gospel - which is in Greek metanoia, or “turning around”; that is, repenting and living a new life.
It is beyond me why some people react the way you do; as if somehow some hoy rituyal has been debased. Rituals do not exist for themselves; they exist for us and as such they need to have an impact on our life. They need to call us out of complacency, and pay attention to what Christ calls us to. And what He calls us to is a radical change. Being human, it is all too easy to be lulled into an attitude of “yep. Un hunh. Got it” without getting it.
Or there may have been different reasons for the change. I really don’t care what the reasons are; I am there to pause, even briefly, to take stock and see if I am actually living as Christ commands, or if I am just on automatic pilot. Maybe you have it down pat; I know I don’t.
And by the way, it is the Ordinary Form. If that was good enough for Benedict 16, it is good enough for me.
I was an altar boy; over the rare times we had a Solemn High Mass, I was a candle bearer, altar boy, thurifer, and Master of Ceremonies; and was in the seminary in college. It absolutely baffles me that people find the Mass forms so different; I am certainly aware of the differences, but the similarities are far greater than the differences.
