This book is very different from other books I’ve read in this sphere. Not so much about the mechanics of perfoming apologetics but on foundations and self preparation. It identifies three spiritual fortifications: apologetics data and arguments, duty to other souls (charity), and the development of love, patience, zeal, magnanimity and humility. The prayer index is also indispensable!
“The soul of apologetics is love because above all it is a work of love.”
