Book excerpt: It is the conviction of Sacramentum Caritatis as well as the fathers of the Second Vatican Council that active participation at Eucharistic celebration cannot be easily disassociated from active involvement in the Church's mission in the world. This present study in the light of the foregoing presuppositions, exposes some of such challenges confronting the Afro-Igbo Christian, with special focus on the menace of the osu caste system, and proposes ways towards its eradication. One of such ways remains strengthening the Eucharistic celebration through the process of the inculturation.
