The prayer was from the St Petersburg diocese in support of the APA appeal for 2019.
I believe that the prayer came from the Bishop of our diocese in regards to the Lentin appeal. It may be available on the diocese's website, or from our parish office.
I am not entirely sure if I am talking about the same thing you are asking but I do know that after each Mass today we are doing the blessing of the throats, which might be what you are referring to if they decided to do it before Mass instead of after.
Thanks! Your answer is awaiting moderation.
