In this post, I offer my understanding of evangelism as a Christian
practice. As I develop this understanding and situate evangelism within
the broader calling and mission of the church, I will compare and
contrast it to the theologies of evangelism offered by William Abraham
and Bryan Stone.Walt Klaiber is quite right when he notes that biblical usage of terms surrounding evangelism and mission are not uniform, and equally right when he suggests that it is less important to argue for a “right” designation of scope than to clarify how it is that one intends to use these terms. In this spirit, I suggest speaking of the calling of the church as inclusive of worship, fellowship and witness. Worship refers to those practices which manifests a proper love for God. Fellowship entails the practices which express the church’s love for one another, and witness, includes the cluster of practices that enact the church’s love for the world. In an important sense, both worship and fellowship do witness, but they do so in a passive mode, since their orientation is more directly to God or the fellowship than to the “watching world.” This passive witness is “before” the world but active witness is purposefully “for” the world. Active witness can also be labeled mission and it includes the pluriform ways in which the church participates in the missio dei—God’s pluriform action in history toward the new creation. Among these modes of active witness are included social action, environmental stewardship, ministries of compassion, and evangelism, among others. Evangelism, then, is the form of witness which hopes to join the missio dei in the creation of a new redeemed humanity.
Evangelism, as a Christian practice, is fundamentally a dimension of the Church’s participation in the activity of the Triune God. Therefore, the primary agent in evangelism is God, who brings humans “from the kingdom of darkness into the kingdom of the Son.” I describe this divine work, employing language familiar to evangelistic literature, as a holistic conversion. I must immediately clarify that this conversion is not to be regarded, as it has regularly has, as a mere decision of the will, or cognitive assent—though both will and mind are deeply involved. Conversion is a holistic process akin to learning a new language, joining a new social group, receiving a new history, and undergoing a paradigm shift. [I've posted on conversion here and here.]
The church’s practice of evangelism, then, is a stewardship of and a participation in God’s holistic work of conversion within people by which they become full citizens in the reign of God, through and in the church. The church’s participation with God’s work of holistic conversion takes the primary forms of invitation and initiation.
Two substantial proposals, those of Abraham and Stone, contribute to development of these two modes.
