This article offers a critical reflection on the World Council of Churches Conference on World Mission and Evangelization in 2018 in Arusha, asking for a renewed focus on and discussion of ecumenical and missional theology, especially the relation between unity and diversity among churches and Christians. Based on an outline of the ecumenical discussion on “unity and (reconciled) diversity,” the author asks for a strengthened focus on the unity of the church. She claims that transforming unity is important for the credibility of the church in its communication of the gospel to the world, that transforming unity is a “matter of survival” in times of secularization and in times of religious persecution, and that transforming unity implies a call to diakonia as an unnegotiable part of God’s mission to the world. Concluding, the author asks for further theological discourse on important themes lifted up by the Arusha Conference, like “mission from the margins,” the work of the Holy Spirit (pneumatology), deification/sanctification/theosis, and the relation between unity and diversity in worship and spirituality. Finally, the author underlines that the Arusha Conference was an important reminder of God’s call to the churches for the ongoing mission of transforming unity.

上帝的使命是改变合一的呼召

本文对 2018 年在阿鲁沙举行的世界教会理事会世界宣教和福传会议进行了批判性反思，要求重新关注和讨论普世和宣教神学，尤其是教会与基督徒之间的统一与多样性之间的关系。根据关于“合一和（和解的）多样性”的大一统讨论的大纲，作者要求加强对教会合一的关注。她声称，转化合一对于教会向世界传播福音的可信度很重要，转化合一是世俗化时代和宗教迫害时期的“生存问题”，转化合一意味着呼唤 diakonia 作为上帝对世界的使命不可谈判的一部分。总结，作者要求就阿鲁沙会议提出的重要主题进行进一步的神学论述，例如“边缘的使命”、圣灵的工作（气动学）、神化/成圣/神学，以及崇拜中统一与多样性之间的关系和灵性。最后，作者强调，阿鲁沙会议是一个重要的提醒，提醒我们上帝呼召教会执行持续的转变合一的使命。
