Which Pope said this?

Pedro Gabriel, MD, is a Catholic layman and physician, born and residing in Portugal. He is a medical oncologist, currently employed in a Portuguese public hospital. A published writer of Catholic novels with a Tolkienite flavor, he is also a parish reader and a former catechist. He seeks to better understand the relationship of God and Man by putting the lens on the frailty of the human condition, be it physical and spiritual. He also wishes to provide a fresh perspective of current Church and World affairs from the point of view of a small western European country, highly secularized but also highly Catholic by tradition.
