No single book has stirred more interest or stimulated more thought about Christian catechesis and its scriptural-liturgical orientation. Appearing first in 1936 it gave new impetus to the renewal of interest in religious education which began at the turn of the twentieth century with a re-examination of methods of teaching. Our religion is an organic unit, in which we must discern a fundamental core which we have to proclaim emphatically…This core is the message of Christ…Our way back to the Father is in union with Christ, through the working of the Holy Spirit. All the other truths of our religion have to be explained from this standpoint and with this perspective. What we teach is the gospel—the good news that Christ is among us. The full impact of its thought is being felt in every corner of the Christian world, especially in the American Catholic school classroom where the new catechetics draws strength and vitality from strong roots planted there in our catechetical past.
