After the death of St. Josemaría in 1975, his successor, Blessed Alvaro del Portillo, had an Audience with Pope St. Paul VI. Referring to the teachings of the founder of Opus Dei, St. Paul VI asked that all these be carefully collected “because they are now already a treasure which belongs to the whole Church.”

This volume contains the first four Letters of some thirty-eight of a foundational nature which St. Josemaría Escrivá wrote. Although they were addressed to all members of Opus Dei, they are valuable resources for everyone in the Church.
