Happy Feast of the Chair of St. Peter!
Yes, there is an actual, physical “Chair of St. Peter” housed at the Vatican. I’ve seen it! Jimmy Akin, can tell you everything you need to know about it and this feast, if you click here.
But what to do about it, today, with your kids? That *I* can help with.
Here’s what we do:
Candy chairs of St. Peter can be made from pretty much anything you have lying around. We usually use some prepackaged cookies and candy, and frosting or royal icing to hold them together.
My kids really look forward to it, especially since most years this feast falls during Lent.
Happy Feasting everyone!
