Simonetta Carr’s book Irenaeus (Christian Biographies for Young Readers) retells the true story of Saint Irenaeus, who was an early Church Father and apologist in the second century AD. The story is set against beautiful pages, showcasing lovely illustrations. Though this book is aimed towards children aged 8 to 12 years, it is also quite interesting for adults. Irenaeus’ faithfulness, discernment, and perseverence is truly inspiring, and Irenaeus also serves as an important historical lesson.  Carr’s book is a wonderful way for children to learn about an important historical figure and key player in the formation of early Christian theology.
