I’ve already copied it. Where did it come from? Sounds to me like a made up thing. I have never ever read any reference to the Blessed Virgin having “altars.”
If you got it from a book, just tell the title and author. Not everything is online.
Perhaps you need to heed your STUDY STUDY STUDY advice and READ your December Devotion.
Does it still sound to you like a 'made up thing'?? LOL! I'm sure by now you are wishing you had not said that....rofl
Get back to me with the "altars" today and the Throne in Heaven.
