I haven't read it myself, but I want to. My parish uses it as its RCIA curriculum!

Congratulations, Trent! I'm so pleased to hear your wife followed you so quickly.

Well, they said it was for idiots.

I read the "Idiot's Guide to Catholicism", and one of the persistent themes was that of dissent. For example, one caption on the priesthood said "Only men can become priests in the Catholic Church, but someday, that will change."
Talk about idiots leading idiots.

In early 2003 I began to look for a church home. I was raised in the Nazarene and Baptist traditions, but decided that I needed to investigate other denominations. I said to myself, "Ahh, what the heck? To be fair I'll even look into the Catholic Church."
So I bought a copy of "Catholicism for Dummies" and this book (along with many others by Hahn, Shea, etc.) helped to bring me home. I was received into the Church at the end of May that year, my newborn daughter was baptised in February, and my wife was received into the Church just this month! Praise God for His goodness! And for the workers in His vineyards like Frs. Trigilio and Brighenti.
I recommend this book to anyone who might have questions about the Church, especially to Protestant friends and family.

It may not be "book snobbery," though. Some of the "Catholicism" books produced in similar series, as Jimmy pointed out, can be very problematic. If people heard you speaking well of "For Dummies" and thought you meant "For [the other leading brand]," I can understand bad reactions.

This was one of the first books I ordered from Amazon, when I was considering conversion, this and Scott Hahn's 'Rome Sweet Home', really helped to convey some of the richness of Catholicism, but more specifically, why I didn't have any options left for remaining protestant.
It's sad that this has become something of a 'joke in some circles (book snobbery, who'da thought it?) but I still refer to it even now I'm a fully fledged Catholic!
God bless.

I have been amazed by how good this book is.
