From then on he worked relentlessly as a pediatrician, educator, and fund-raiser doing it all for the glory of God, “putting on Jesus Christ” until becoming himself Opus Dei.

In spite of obstacles that include political strife, and social and economic challenges, he remained faithful to his land and people through his work as a doctor It is an extraordinary lesson on how one’s ordinary work can be converted into a tool of service and improvement for all of society.
