Cardinal Joseph Cardijn

The history of YCS is linked to the life and vision of Cardinal Joseph Cardijn, a pioneer of Catholic Social Action and Lay apostolate in the church.

Cardijn was a strong believer that human beings are created in the image of God have to live in dignity. However, the reality of society, where majority of people were living in de-humanized situations, was contradictory to this belief. He promoted organized people's movements, using the pedagogy of See - Judge - Act, to change this contradiction.

Cardijn initially started International Young Christian Workers (IYCW) Movement in 1925, but later, students inspired by its impact, initiated the International Young Christian Students (IYCS), using a similar approach. Cardijn strongly believed that Workers are the best apostles amongst Workers and so the Students.
