~Now that Summorum Pontificum is in full force, I thought I'd repost this link to A Child's Missal from The Society of St. John which beautifully explains The Holy Sacrifice of the Mass. The illustrations come from a deep immersion in iconographic language and the pictures of the Mass show its timelessness. It's great even for adults. So if you're looking for a resource to teach the Mass, this is a fine one to add to your library. Best of all, you may download the complete book in pdf. However, it is worth getting hardbound.

I attended a conference with Steve Wood as one of the featured speakers and he said that if your child's catechetical book has butterflies and balloons on the cover, "Run away!"
