Drawing on the International Methodist – Catholic report on The Call to Holiness, this article identifies holiness as both a divine attribute and as a Christian imperative, inextricably linked with the unity of Christians and of humanity. For humanity to be in the image and likeness of this holy God implies a participation in God’s holiness. Because human life is inescapably social, it implies that this holiness must be expressed in social interaction. For the life of the Christian Church to reflect the holiness of God requires a commitment to unity and actions that echo that commitment. This paper traces the biblical basis of the Judaeo-Christian belief in the holiness of God. It goes on to examine the obstacles and opportunities for Christian unity, particularly between the churches of the Wesleyan tradition and the Church of Rome.
