In the three short years of Oscar Romero's episcopal ministry he emerged as a courageous prophet, a voice for those who had no voice, and truly a saint for our time. Nowhere is his theological and pastoral vision so clearly expressed as in the four pastoral letters he released from 1977-1980. Along with the other documents collected here, they represent one of the most powerful expressions of church teaching in our time: an application of the gospel to the challenges of history, especially in situations marked by injustice, inequality, and violence. These documents, sealed by his own blood, are a timeless call to follow the Good News of Jesus, wherever it leads.
