Abstract
Cullman, a distinguished Swiss Protestant theologian, presents a practical proposal for realizing Christian solidarity. He concedes, first, that opposing views on the concept of the Church make actual church unity humanly impossible for contemporary Protestants and Catholics. He proposes that a collection be taken up among Protestant churches for the Catholic poor and among Catholic churches for the Protestant poor. An adaptation of Paul's suggestion, this "exchange" offering would, he hopes, foster an atmosphere in which theological debate could flourish. -D. D. O.
