The Social Doctrine of the Church is a living reality, in dialogue with history, cultures and sciences. At the same time, it enshrines a core set of unchanging truths. For this reason, it can be considered a form of wisdom that is capable of guiding the personal and societal lives of believers even today. In this second chapter, I would like to focus on some of the foundations and principles of the Church’s Social Doctrine that will help us to interpret the “new things” of our time, particularly in view of the inherent dignity of the human person. In order to protect the human person in the age of artificial intelligence, I believe that today we must once again reflect on the common good, the universal destination of goods, subsidiarity, solidarity and social justice. I am convinced that a harmonious relationship between these principles requires that they be considered collectively, so that it becomes clear how they relate to and complement each other.

In offering these reflections, my hope is, first and foremost, to help the lay faithful and people of goodwill rediscover their duty of implementing the above-mentioned principles in their daily lives, family relationships, work and involvement in society. Thus, they will let themselves be inspired by the aim of embodying God’s love in the concrete events of life. At the same time, I would like to encourage academic institutions and universities to give fresh impetus to these principles, and to apply them in a way that will be relevant and effective in addressing the digital revolution. In this way, theological and philosophical enquiry will be able to further explore and support the Church’s pastoral journey, and contribute to the Magisterium’s task of enlightening the consciences of the faithful and guiding their efforts to make the life of our societies more just and fraternal.
