The Essential Tillich : An Anthology of the Writings of Paul Tillich Book

This book had a profound effect upon me! By introducing me to christian doctrine, articulated intellectually, it gave new life and a broader range to my faith. Indeed, Tillich was once described as an apostle to the intelligentsia.
It is possible to use existential concepts to steer people's thinking back towards objective, collective realities such as sin, the need for transcendence and the ubiquity of suffering. Even the existence of God and the Human spirit which seem to be in need of constant re-affirmation.
Most notably, Tillich used his own words for such older truths, redefining them in a modern philosphical language and reframing them in more relevant contexts, without departing from their original meaning, sanctity or validity. To my mind, this was a brave step.
Highly recommended but not to everyone.
