Children’s book line Arch Books will celebrate its 50th anniversary in 2015. To begin the celebration, Concordia Publishing House (CPH) will release two new collections of the popular Christian children’s stories this summer.

Best-Loved Parables of Jesus and Best-Loved Christmas Stories will provide families with comprehensive collections of Arch Books’ favorites that tell children the stories of Jesus.

With more than 60 million copies sold, the Arch Books series has engaged children with Bible stories through fun-to-read rhymes and colorful artwork since 1965. Each book features short portrayals of complete Bible stories in 16 pages, aimed at making the messages clear and memorable for children ages 5–9.

“We often hear stories from customers about how they read Arch Books as children, and now they read the books to their children,” said Peggy Kuethe, editor at CPH. “It’s a very unique series because it has been around for so long. It’s truly something that generations of families can share.”

Each book includes a letter to parents, providing in-depth information about the Bible story. This allows them to answer their children’s questions about God and His people as the stories are read.

Two additional anniversary collections, Best-Loved Easter Stories and Best-Loved Miracles of Jesus, will be released early next year.
