Due to the current situation of the ecological crisis, the author takes up the topic of the analysis of the most recent Church Magisterium. He concludes that it is in the light of the documents Laudato si’, Evangelii gaudium, Fratelli tutti, etc. of Pope Francis, that can find a doctrine which (in terms of the need for ecological conversion) is normative, although informal and take the conviction that maybe this doctrine in line with the words of Cardinal Coccopalmiero, former president of the Pontifical Council for Legislative Texts, will soon be introduced into the Code of Canon Law.
