"The mystery of Christ is so unfathomably rich that it cannot be exhausted by its expression in any single liturgical tradition. The history of the blossoming and development of these rites witnesses to a remarkable complementarity. When the Churches lived their respective liturgical traditions in the communion of the faith and the sacraments of the faith, they enriched one another and grew in fidelity to Tradition and to the common mission of the whole Church." ("CCC" 1201) As catholic or universal, the Church believes it can and should hold within its unity the true riches of these peoples and cultures.
