The first volume of Saint Josemaria's letters (Cartas 1) has just been published as part of the Complete Works of St. Josemaria (Rialp). It contains his four earliest letters. These letters are addressed in a special way to people in the Work. They are helpful to deepen our knowledge of the spirit of Opus Dei, so as to renew our desire to live it each day with greater love of God and to transmit it in our personal apostolate. They will also provide a good source of material for the means of formation.
If you read Spanish, you are encouraged to read it and use it for your prayer. The English translation is being prepared, even though it is not known when it will be available.
The book can be ordered through Scepter at usamadrid.com or scepterespanol.org.
