In this book, bishops, priests, and members of the laity show how we can all participate effectively in this great apostolate of fundamental love of one's neighbour. The emphasis is rightly placed upon lay participation in this holy crusade of sharing the truths of Christ with those who know Him not. The success of this crusade depends in great part on the zeal of our devoted laity. This book shows how they can fulfil this divinely appointed task. It shows how every Catholic can do something by his example, by his works and words to bring Christ into the minds and hearts of those who know Him not, the noble and Christlike objective of the lay apostolate.
