Produced by the Marquette Univerity Institute of Catechetical Research under the editorship of Edward A. Fitzpatrick in the 1930's, the Highway to Heaven series of Religion textbooks is a breath of fresh air. Unashamed love of the Catholic Faith is evident on every page.
Full of beautiful black and white woodcut-styled illustrations, The Vine and the Branches is the Fifth Grade text in the series. It covers the history of the people of God after Christ's birth.
The teacher's manuals for this series are called The Religion in Life Curriculum and contain not merely an answer key but an entire Religion Curriculum to accompany the textbook.
