"Lo eterno sin disimulo" (The Undisguised Eternal) is a collection of nine previously published essays and several letters in which Lewis displays his ability to reason rigorously and write lucidly about Christianity.
To speak of the eternal, without masks, without pretense, without deception – that is the task Lewis undertakes in this substantial book. And to do so, he uses very different means: a scholarly lecture, a colloquium, a debate, a conversation among friends, a newspaper article, a letter...
Every occasion is good for bearing witness to faith and timeless truth, "to show everyone unheard-of news of plenitudes," with an apostolic zeal that challenges us. And Lewis approaches it with his proverbial clarity, lucidity, and sharpness.
