St. Peter Claver was a Spanish Jesuit missionary who dedicated his life to serving African slaves in Colombia. Known as the "Slave of the Slaves," he baptized and ministered to over 300,000 enslaved people, providing them with food, medical care, and spiritual guidance. His tireless efforts for human dignity and justice made him one of the greatest missionaries of his time.
St. Peter Claver was born in Verdu, Spain, in 1580. He entered the Society of Jesus (Jesuits) and, inspired by a fellow Jesuit missionary, St. Alphonsus Rodriguez, felt called to serve in the Americas. In 1610, he traveled to Cartagena, a major port in present-day Colombia, where thousands of enslaved Africans were brought in chains to be sold.
From the moment he arrived, Peter devoted himself to their care. Ignoring the harsh conditions and disease-ridden environment, he would meet the arriving ships with food, water, and medicine. He personally tended to the sick, comforted the suffering, and shared the love of Christ with those who had been torn from their homeland. He preached in their languages and ensured they received the sacraments, especially baptism.
Despite opposition from slave traders and colonial authorities, Peter Claver fearlessly continued his mission for over 40 years. He baptized an estimated 300,000 people, often advocating for their humane treatment. His compassion extended beyond the enslaved—he also worked with the poor, the sick, and prisoners.
In his later years, Peter fell ill and spent the last four years of his life neglected and forgotten. He died on September 8, 1654. After his death, his incredible legacy was recognized, and he was canonized in 1888. He is now honored as the patron saint of missionaries, African Americans, and human rights defenders.
