Moreover, from the 1930s, when Japan underwent huge pressures from State Shinto, people were acutely aware of the danger of commitment to other religions. At that time, the NCC Center for the Study of Japanese Religions was established to function as an outreach institute between Christianity and other religions in Japan. And from the Catholic side, the Oriental Religion Research Center and the Nanzan Institute for Religion and Culture were established. In particular, since the Second Vatican Council, the Catholic Church has tried to deal with interreligious dialogue constructively. Dialogue is not a substitute for missionary work.
Missions is a necessity for religious faith.
Those who have experienced the truth are willing to convey the truth, living in joy, to others. Christianity has been practicing the world mission given in Jesus' Great Commission which is recorded at the end of the Gospels. Yet, this is not just an order. Interacting with the internal necessity by which Christians cannot help conveying the Good News to others, it is quite possible to begin to do the Great Commission. Today, having much dialogue does not imply not doing that mission.
