In an interview in "30Days", 3-2004, accessed 17 February 2013, Cottier remarked: "Going back to the early years, the first "big" text I worked on was the social encyclical Centesimus annus. And then the Ut unum sint on ecumenicalism, the moral encyclical Veritatis splendor, and the Fides et ratio... also the Catechism of the Catholic Church".
