I learned about Paul and Joan Plum when I was lucky enough to run across their latest book Teach Me about a Church Inside & Out: Discussions and Activities for Children. This simple yet expansive paperback introduces children and their parents to the various items related to our Church and Catholic liturgy. Alphabetically, the book defines terms from Altar to Vestment, providing informative descriptions, outline illustrations suitable for coloring, and interactive elements to engage the reader. I have found this book to be an excellent teaching tool with my own children, especially my young Thurifer. If you don't know what a Thurifer is, you too will benefit from reading Teach Me about a Church Inside & Out: Discussions and Activities for Children.
