If you said "the third day in the Easter Octave", some might chide you for being archaic and not with it (whatever the heck "it" is).
You silly geese! It's Earth Day! Did you let this stupendous event go by, as I almost did (stop yawning!)? I think we can be grateful that April 22 is during the Easter Octave this year; else the politically-correct yammering about the Catholic Climate Covenant would be much louder than it is now. As it is, the nonsense reigns at Blessed Sacrament in Chevy Chase.
By the way - read about Ira Einhorn who claims to be one of Earth Day's founders. He's a convicted murderer! What a guy! He holds human life cheaply, obviously. Why give him and his crackpot notions any moral credibility?
