[Edit: Sorry -- Posted this in the wrong place the first time!
When I was first looking for a web site with a reading plan for the Catechism, someone on another forum suggested that I organize my own -- which is how the wiki page
Someone (maybe even the same person) also suggested that the readings be organized according to the liturgical calendar. I was eager to get started at the time and so didn't do that, but I think it's a great idea.
So I've started a new wiki page for that effort. Here it is -- I hope you all will join in!Liturgical Catechism Readings
Oh, and if anyone can find an existing web page that provides this kind of thing, please let me know. It's a worthwhile thing to do if no one has done it before, but I'd be oh so glad to use an existing one!
