We spoke of the moment at which history, in terms of a concrete situation, had matured to the point of being able to receive the breakthrough of the central manifestation of the Kingdom of God. The New Testament has called this moment the fulfillment of time, in Greek, kairos.
This term has been frequently used since we introduced it into theological and philosophical discussion in connection with the religious socialist movement in Germany after the First World War. It was chosen to remind Christian theology of the fact that the biblical writers, not only of the Old but also of the New Testament, were aware of the self-transcending dynamics of history. And it was chosen to remind philosophy of the necessity of dealing with history, not only in terms of its logical and categorical structure only, but also in terms of its dynamics.
And, above all, kairos should express the feeling of many people in central Europe after the First World War that a moment of history had appeared which was pregnant with a new understanding of the meaning of history and life. Whether or not this feeling was empirically confirmed – in part it was, in part it was not – the concept itself retains its significance and belongs in the whole of systematic theology.
Its original meaning – the right time, the time in which something can be done – must be contrasted with chronos, measured time or clock time. The former is qualitative, the latter quantitative. In the English word, timing, something of the qualitative character of time is expressed, and if one would speak of God’s timing in his providential activity, this term would come near to the meaning of kairos.
In ordinary Greek language, the word is used for any practical purpose in which a good occasion for some action is given. In the New Testament it is the translation of a word used by Jesus when he speaks of his time which has not yet come – the time of his suffering and death. It is used by both John the Baptist and Jesus when they announce the fulfillment of time with respect to the Kingdom of God, which is at hand.
Paul uses kairos when he speaks in a world-historical view of the moment of time in which God could send his Son, the moment which was selected to become the center of history. In order to recognize this great kairos, one must be able to see the signs of the times, as Jesus says when he accuses his enemies of not seeing them.
Paul, in his description of the kairos, looks at the situation both of paganism and of Judaism, and in the Deutero-Pauline literature the world-historical and cosmic view of the appearance of the Christ plays an increasingly important role.
We have interpreted the fulfillment of time as the moment of maturity in a particular religious and cultural development – adding, however, the warning that maturity means not only the ability to receive the central manifestation of the Kingdom of God but also the greatest power to resist it. For maturity is the result of education by the law, and in some who take the law with radical seriousness, maturity becomes despair of the law, with the ensuing quest for that which breaks through the law as good news.
The experience of a kairos has occurred again and again in the history of the churches, although the term was not used. Whenever the Prophetic Spirit arose in the churches, the third stage was spoke of, the stage of the rule of Christ in the one thousand – year period. This stage was seen as immediately imminent and so became the basis for prophetic criticism of the churches in their distorted stage. When the churches rejected this criticism or accepted it in a partial, compromising way, the prophetic Spirit was forced into sectarian movements of an originally revolutionary character – until the sects became churches and the prophetic Spirit became latent.
The fact that kairos-experiences belong to the history of the churches and that the great kairos, the appearance of the center of history, is again and again re-experienced through relative kairoi, in which the Kingdom of God manifests itself in a particular breakthrough, is decisive for our consideration.
The relation of the one kairos to the kairoi is the relation of the criterion to that which stands under the criterion and the relation of the source of power to that which is nourished by the source of power. Kairoi have occurred and are occurring in all preparatory and receiving movements in the church latent and manifest, for although the prophetic Spirit is latent or even repressed over long stretches of history, it is never absent and breaks through the barriers of the law in a kairos.
Awareness is a matter of vision. It is not an object of analysis and calculation such as could be given in psychological or sociological terms. It is not a matter of detached observation but of involved experience. This, however, does not mean that observation and analysis are excluded; they serve to objectify the experience and to clarify and enrich the vision. But observation and analysis do not produce the experience of the kairos. The prophetic Spirit works creatively without any dependence on argumentation and good will. But every moment which claims to be Spiritual must be tested, and the criterion is the great kairos.
