The Open Secret is based on a series of lectures that Lesslie Newbigin delivered to equip men and women for missionary service. His focus is practical in nature, written for the person with "little time for leisurely academic study" (loc. 15). The thesis of his book is that God has an open secret which is that through Christ, he will "bring all things to their true end in the glory of the triune God" and that this message is "announced in the gospel that is preached to all the nations” (loc. 2557). The first three chapters overview the history of missions as well as the authority by which the message goes forth in. Chapters 4-6 explain the mission of God through a Trinitarian framework. He does this by describing Christian mission in three ways, as: "proclaiming the kingdom of the Father, as sharing the life of the Son, and as bearing the witness of the Spirit" (loc. 401). The final four chapters examine how mission relates to several contemporary issues.
The Mission of God
Newbigin says that mission is the "proclaiming of the kingdom of the Father, and it concerns the rule of God over all that is" (loc. 1653). This is a helpful definition that encompasses two separate aspects that different Christians emphasize. There are some who see mission "primarily in terms of action for God's justice" (loc. 158) and others who see it "primarily in terms of personal conversion" (loc. 159). True missions encompasses both aspects where believers take "with full seriousness both the call to personal conversion and the call to action for God's justice in the world" (loc. 143). Newbigin aims for his book to help people move past this binary dichotomy.
With a definition of mission set, he tears down the erroneous assumption that missions are only for missionaries. It is not that one church can choose to be on mission while another does not, rather, "a church that is not 'the church in mission' is no church at all" (loc. 45). Neither is missions to be carried out by the rich and powerful nations exclusively. Though the missionary movement has been historically connected with the Western world and the colonial expansion. In a post-colonial era, Western Christians "are no longer accepted as leaders by the rest of the world" (loc. 167). Therefore, the West will need to accept carrying out the mission of God not from a position of power but from weakness.
If mission is proclaiming the kingdom and rule of God, a fair question to ask is "by what authority" is this message being carried out in? He answers that the supreme authority is Jesus who claims, "the allegiance of all peoples" (loc. 228). This Jesus is "the Son, sent by the Father and anointed by the Spirit to be the bearer of God's kingdom to the nations" (loc. 331). Newbigin argues that the full answer to who Jesus is can only be described in Trinitarian language. Therefore, to speak in Jesus' name is to speak "In the name of the Father, the Son, and the Holy Spirit" (loc. 388). In the next section of his book, he explains the mission of God through each of the three persons of the Trinity.
The Trinitarian Mission
The kingdom of the Father is the biblical story of God's "blessing for all the nations" and "the action of God to bring history to its true end" (loc. 459). This contrasts with a common misconception that salvation is "a way of escape for the redeemed soul out of history" (loc. 459). The kingdom is not just for Israel, nor is it just for the individual, but is for all nations. This is manifested in Jesus by "the reign of God hidden and manifest in the dying of a condemned and excommunicated man" (loc. 493).
The life of the Son is the fact that through Jesus the kingdom of God is present. Through his incarnation he was able to say, "the kingdom of God is in the midst of you” (ESV, Luke 17:21). Since Jesus is no longer bodily present in the world, it is reasonable to wonder if the presence of the kingdom is removed "with the end of Jesus' earthly ministry" (loc. 603)? Newbigin answers that after the ascension of Jesus, "the church represents the presence of the reign of God in the life of the world" (loc. 753). It is through the community of saints where the nations get a taste of the kingdom of God.
The agent of mission in the world, is the Spirit of God. The church is not the strong triumphalistic leaders, but rather the weak and fumbling ones. It is the Spirit who leads and guides. When Paul wanted to go bring the message of Jesus into Asia it was the Spirit who forbade him (Acts 16:6), because it was not the right time. Paul was not the leader, the Spirit was. Likewise, the church was in hiding until Pentecost, but once they were empowered by the Holy Spirit (Luke 24:49), that is when they became bold and went out to spread the message of Jesus. Thus, it is "by an action of the sovereign Spirit of God that the church is launched on its mission. And it remains the mission of the Spirit" (loc. 805).
The Gospel and Contemporary Issues
After defining the mission of God, and explaining it through a Trinitarian framework, Newbigin shifts to how the mission relates to several contemporary issues. He first examines the intersection of the particularity of God's salvation with the universal acting of God in the world. He then looks at mission through the lens of justice (specifically the claims of Liberation theology) and church growth culture. Finally, he examines how mission intersects with other religions in inter-faith dialogue.
It is the doctrine of election which makes it so that "universality and particularity do not contradict one another" (loc. 924). This is the belief, especially taught in Ephesians 1:3-14 that explains "God's action in choosing and calling a particular people" (loc. 975). He holds that a proper understanding of election will affirm that 1) God desires all to come to him. 2) People are not chosen because they are superior 3) The covenant God makes with his elect is not a contract that is upheld by obedience (loc. 1065-1072). While these points should not be disputed, Newbigin takes it a step further by arguing that the elect do not have a "privileged status" (loc. 1066). He is not comfortable with any distinctions that confer privilege or blessing to the elect and says that the "plain meaning" of Scripture is that "there is no distinction between Christian and pagan because the same Lord is Lord of all" (loc. 2397). This does not square with the biblical teaching that the church is holy, set apart, and uniquely blessed by God. Jesus prays for the church, not for the world (John 17:9). God disciplines the church because they are his children, whereas others he does not (Heb 12:7-8). The church obtains an inheritance (Eph 1:11-14) which the unrighteous do not obtain (1 Cor 6:9). Though it is difficult to pin down the specifics of Newbigin's view on salvation, he seems to hold to some form of Christian inclusivism. He says that the unbelief of the Jews is "not for their destruction, but for their ultimate salvation" (loc. 1072). This belief is articulated in different ways in the final chapter on inter-faith dialogue.
Newbigin then affirms that the mission of God has a justice component while he also rejects measuring results through church growth. While not agreeing with all the claims of Liberation theology, he affirms that knowing God is not merely "a matter of intellectual contemplation or mystical union" (loc. 1331) but is "doing justice and mercy in concrete situations" (loc. 1331). While this is true, he understands capitalism as the problem instead of the solution. He calls the idol of the free market the "most urgent missionary task during the coming century" (loc. 1303) and frames landowners and corporations as those who exploit "for their own profit" (loc. 1325). While Crony Capitalism is known to exploit, a truly free market does not. When there is no coercion or government involvement in trade, free transactions are win-win exchanges where people receive what they most desire, either money or goods.
Newbigin seems to be influenced by Karl Marx's labor theory of value, though this is not made explicit in his writing. Even though I believe Newbigin identifies the wrong enemies, his point still stands that the church must be involved in helping the poor and establishing justice as a core aspect of mission. The apostles told Paul and Barnabas as they went on mission to "remember the poor" which Paul said is "the very thing I was eager to do" (Gal. 2:10).
The last issue Newbigin deals with is inter-faith dialogue. He speaks of two different approaches which he labels as "confessional" (Jesus is Lord of all) and "truth-seeking" (the Transcendent Being is infinitely greater than one's limited view of it) (loc. 2240). He advocates for the truth-seeking position which does not have the conversion of a sinner as the primary goal. Rather, it takes a listening approach where there is genuine openness to even the possibility that another's way of understanding the world is the one that is right (loc. 2502). He says it is impossible to have a friendly and honest conversation if one thinks "that I am one of the saved and he is one of the lost" (loc. 2355). Due to seeing the mission of God as the restoration of the cosmos, Newbigin believes it is unhelpful to speculate "which of these monads will finally reach the goal and which will not" (loc. 2413). In other words, he does not believe people should be looked at as individuals when it comes to salvation since God is going to restore the entire world. While Newbigin rejects universalist conclusions, he does seem to affirm Christian inclusivism. This leads him to overcorrect by looking at people almost entirely as a whole instead of also being concerned with individual salvation. Jesus affirms that the angels rejoice over one sinner who repents (Luke 15:7), showing that faith and repentance on an individual level is important. Newbigin does not completely reject considering people as individuals, but rather he rejects the believer seeing themselves as the one's who are in a privileged position, having special access to God, and the right answers. The problem is the believer is all of those things, and it is not arrogant to believe so. They did not earn those positions by effort or because there was something good in them, but they were bestowed privilege and truth because they are recipients of grace.
The Open Secret and My Ministry
Throughout this book, Newbigin traces the paradox of the kingdom, something that is both open and yet a secret. The secret is that God is reconciling the world to himself, and this is being proclaimed openly through the church to all nations. This book is helpful in that it does not look at mission as an add-on, but as core to the church's identity. It also confronts the individualistic tendencies that are common in the Western world by reminding readers that God's plan is cosmic in nature. Unfortunately, Newbigin is also a product of his culture and thus carries unhelpful influences from Marxism, Liberation Theology, and Inclusivism into this book. In order to be on mission, there must be a message-bearer. Contrary to Newbigin, it is imperative that we as the church share the gospel authoritatively. We are not sharing our opinion and listening with openness to be potentially convinced of a contradictory truth. Rather, we possess the truth and are proclaiming it with authority, as the King's ambassador (2 Cor. 5:20). I therefore accept Newbigin's understanding of the definition and importance of mission but believe the approach of how mission looks practically is more influenced by his life experience in a pluralistic culture, than the exclusivist understanding found in the New Testament.
