While I certainly want to see children fully participate in the liturgy (as I did back when dinosaurs ruled the earth despite the Mass being in Latin when I was very young, and in the form we currently know as I entered the teens–in those ‘in between years’ we certainly had full participation no matter what the language was), I disliked the “Eucharistic Prayers for Children” for precisely the reason given that they are now to be removed–a de-emphasis of the sacred due to the well-intentioned (but mistaken) belief on the part of some that children just would not be able to ‘understand’ such things and needed to have things put on ‘their’ level. To an extent, that is true–one does not try to teach a 1st grade class English composition by sitting them down with Shakespeare’s plays alone–but one does not either 'bowdlerize" Shakespeare to make his language the equivalent of that of a 6 year old, nor does one completely exclude him because ‘children will not understand’. They will not understand thoroughly but they will understand something, and the repetition as they grow older will make things more and more clear, and so they certainly need SOME exposure, and regularly.
To me, taking the Eucharistic Prayers and making separate ‘sets’ for children, using them for X number of years and then abruptly sending said child off and expecting them to suddenly be both familiar with, and appreciative of, “regular adult” prayers–and ‘regular adult concepts’ that they were unfamiliar with and probably viscerally disliked (because of the unfamiliarity, especially in the last few ‘me centered’ decades) was a very short-sighted move. I’m glad it is being corrected, but I’m glad, I think, for the right reason … . not because I ‘dislike’ the idea of children’s prayer per se, but because this particular concept was carried out badly. With good intentions. . .but badlyl
