Edward Cornelis Florentius Alfonsus Schillebeeckx was a Belgian Roman Catholic theologian born in Antwerp. He taught at the Catholic University in Nijmegen. He then continued writing. In his nineties, he still wanted to finish a major book about the Sacraments.
He was a member of the Dominican Order. His books on theology have been translated into many languages, and his contributions to the Second Vatican Council made him known throughout the world.
I read the introduction and chapter 2 "Mary's Place in the History of Redemption" (43% of the book) for my Systematic Theology II course under Dr. Jacob Lett for a research paper I was writing on Mary, the mother of Jesus. It was dense at times but provided keen insights into Mariology from a devout 20th century Belgian Roman Catholic scholar.
