Saints Priscilla and Aquila were a first-century Christian missionary married couple described in the New Testament. Aquila is traditionally listed among the Seventy Disciples. They lived, worked, and traveled with the Apostle Paul, who described them as his "fellow workers in Christ Jesus" (Romans 16:3). Saints Priscilla and Aquila are described in the New Testament as providing a presence that strengthened the early Christian churches. Paul was generous in his recognition and acknowledgment of his indebtedness to them (Romans 16:3–4). Together, they are credited with instructing Apollos, a major evangelist of the first century, and "[explaining] to him the way of God more accurately" (Acts 18:26). In Romans 16:3–4, thought to have been written in 56 or 57, St. Paul sends his greetings to Priscilla and Aquila and proclaims that both of them "risked their necks" to save Paul's life. Tradition reports that Aquila and Priscilla were martyred together. They are regarded as saints in most Christian churches that canonize saints. In the Catholic Church, the Roman Martyrology lists their feast as July 8, the Orthodox Church commemorates Aquila alone as one of the seventy disciples on January 17.
