at the Social School. His interest ranged from economics and sociology to philosophy and pedagogy. He understood his own role as chaplain of Catholic Action, as that of an animator, and above all, an educator. He made an effort to convince, especially young people, of the importance of training, and often repeated quotes such as "Teaching and education are the first company of a community, if you do not want all kinds of companies to become stagnant or half developed”, “Man is made through training”, “It is better to light a match than to curse the darkness”, or “Sowing in time is professionally training our young people.

He conceived the magazine as "a constant invitation to dialogue, relationship and cooperation for the practical application of the postulates of social justice in the business environment, in a climate of freedom and love, indispensable in a work community”. He considered work as
