In January 1957 Professor Oscar Cullmann was invited to lecture in Zurich on the subject, ‘Primitive Christendom and The Ecumenical Problem’. Referring to the collection made by the early Gentile Christians for the Jewish Christians, he proposed that the separated Christians of today make a reciprocal collection at least once a year, as an expression of brotherhood. In a later article, Professor Cullmann defined the significance and the form of this collection more narrowly, and answered objections. We would like to reproduce his thoughts here and to assess their value.

For over fifty years Catholics and non-Catholics have been praying during the same octave every year for unity in faith. This is a promising sign, and we would not be far wrong if we saw here the basic fact and the supreme form of the movement towards re-union. Further, we note as novelty that theological work, which formerly accentuated differences, is now in many respects leading scholars back together along various directions. Thus, for example, for some twenty or thirty years there has been a lively and fruitful exchange in Biblical studies between Catholic and non-Catholic exegetes. Even in the sphere of systematic theology there have been many changes. Without applauding every attempt to seek a rapprochement in content and method, we must not underestimate the value of this tendency, first to reach agreement on several points, and then to make possible a non-polemical, even friendly conversation on the points which still divide. Cullmann is not content with this.
