Arinze was born in Eziowelle, Anambra, Nigeria. A convert from an African traditional religion, he was baptized on his ninth birthday (1 November 1941) by Father Michael Tansi, who was beatified by John Paul II in 1998. His parents later converted to Catholicism. At age 15, he entered All Hallows Seminary of Onitsha from which he graduated and earned a philosophy degree in 1950. His father was initially opposed to his entering the seminary, but after seeing how much Francis enjoyed it, he encouraged him. Arinze stayed at All Hallows until 1953 to teach. In 1955, he went to Rome to study theology at the Pontifical Urban University, where he ultimately earned a doctorate in sacred theology summa cum laude. On 23 November 1958, at the chapel of the university, Arinze was ordained to the priesthood by Gregorio Pietro Agagianian, pro-prefect of the Sacred Congregation for the Propagation of the Faith (Propaganda Fide).
