The Jesuit priest who baptized 300,000 enslaved people in the heart of Cartagena

In short: Peter Claver spent four decades in the New Kingdom of Granada, boarding slave ships to offer food and comfort to those arriving from Africa. While he is celebrated as the patron saint of slaves, his complex legacy remains a subject of intense historical debate regarding his methods and beliefs.

Born in 1580 to a prosperous Spanish farming family, Peter Claver entered the Society of Jesus at age 20. Influenced by the laybrother Alphonsus Rodriguez, who prophesied his future in the colonies, Claver arrived in Cartagena in 1615. He worked under his mentor, Alonso de Sandoval, who had spent 40 years documenting African customs and rites. Claver eventually adopted the title 'servant of the Ethiopians forever,' dedicating his life to the spiritual and physical care of enslaved Africans who survived the brutal Atlantic crossing.

Claver’s ministry was defined by his presence at the port. He would board incoming ships to provide citrus, water, and tobacco, aiming to establish trust before the enslaved were sold. He utilized translators and mnemonic devices to teach the Catholic catechism, often rewarding those who learned the doctrine. Beyond his work at the docks, he traveled to plantations to offer spiritual consolation, famously refusing the hospitality of overseers to lodge instead in the slaves' quarters. By the time of his death in 1654, he had baptized an estimated 300,000 people.

Despite his reputation as a moral force, Claver’s legacy is contested. While he advocated for humane treatment, he also worked to suppress African spiritual practices, which he viewed as heretical. Modern critics, such as Katie Grimes, argue that his canonization in 1888 potentially upholds anti-blackness. Conversely, supporters point out that he granted his own slaves uncommon freedom and that his use of physical punishment was intended to prevent what he deemed immoral behavior. Today, his influence persists through organizations like the Knights of Peter Claver and the Stella Maris maritime ministry, and he is honored in Colombia with a National Day of Human Rights on September 9.
