To recover the missionary dimension of the Church is today’s greatest imperative. We have to recover a very basic truth: that the Church is essentially Mission, that the very roots of her life are in the commandment of Christ: “Go Ye therefore and teach all nations” (Matt. 28:19). A Christian community that would lose this missionary zeal and purpose, that would become selfish and self-centered, that would limit itself to “satisfying the spiritual needs of its members”, that would identify itself completely with a nation, a society, a social or ethnic group – is on its way to spiritual decadence and death, because the essential spiritual need of a Christian is precisely that of sharing the life and the Truth with as many men as possible and ultimately with the whole world. Mission thus is the organic need and task of the Church in the world, the real meaning of Church’s presence in history between the first and the second advents of her Lord, or, in other terms, the meaning of Christian history. Obviously not all members of the Church can go and preach in the literal sense of the word. But all can have a concern for the missionary function of the Church, feel responsible for it, help and support it. In this respect each diocese, each parish and each member of the Church are involved in the missionary ministry.
