I note that this comes under that which has been "proposed." While I'm not a Catholic, it is unclear to me why this isn't a command, and why it isn't first before all things. It seems to me that the should be both public and private confession and repentance happening all over the place.
It has. For instance, my bishop, of Greensburg, PA, made the call for such a day of repentence for the Thursday before Easter. I am sure he is not the only bishop to make such a call. What is being proposed here is a unified national day of repentence.
Please try to understand the mechanism at work here. If you will, this is like a committee recommending that the entire Congress do something. The committee can be behind it 100%, but until Congress meets and approves it, it is still not law.
