The undiscerning observer may think that this mixture of ideal and reality, of the human and spiritual, is most likely to be present where there are a number of levels in the structure of a community, as in marriage, the family, friendship, where the human element as such already assumes a central importance in the community’s coming into being at all, and where the spiritual is only something added to the physical and intellectual. According to this view, it is only in these relationships that there is a danger of confusing and mixing the two spheres, whereas there can be no such danger in a purely spiritual fellowship. This idea, however, is a great delusion. According to all experience the truth is just the opposite. A marriage, a family, a friendship is quite conscious of the limitations of its community-building power; such relationships know very well, if they are sound, where the human element stops and the spiritual begins. They know the difference between physical-intellectual and spiritual community. On the contrary, when a community of a purely spiritual kind is established, it always encounters the danger that everything human will be carried into and intermixed with this fellowship. A purely spiritual relationship is not only dangerous but also an altogether abnormal thing. When physical and family relationships or ordinary associations, that is, those arising from everyday life with all its claims upon people who are working together, are not projected into the spiritual community, then we must be especially careful. That is why, as experience has shown, it is precisely in retreats of short duration that the human element develops most easily. Nothing is easier than to stimulate the glow of fellowship in a few days of life together, but nothing is more fatal to the sound, sober, brotherly fellowship of everyday life. There is probably no Christian to whom God has not given the uplifting experience of genuine Christian community at least once in his life. But in this world such experiences can be no more than a gracious extra beyond the daily bread of Christian community life. We have no claim upon such experiences, and we do not live with other Christians for the sake of acquiring them. It is not the experience of Christian brotherhood, but solid and certain faith in brotherhood that holds us together. That God has acted and wants to act upon us all, this we see in faith as God’s greatest gift, this makes us glad and happy, but it also makes us ready to forego all such experiences when God at times does not grant them. We are bound together by faith, not by experience. ‘Behold, how good and how pleasant it is for brethren to dwell together in unity’—this is the Scripture’s praise of life together under the Word. But now we can rightly interpret the words ‘in unity’ and say, ‘for brethren to dwell together through Christ’. For Jesus Christ alone is our unity. ‘He is our peace’. Through him alone do we have access to one another, joy in one another, and fellowship with one another.
