Whoever takes up the subject of theology discovers himself immediately, recurrently, and inevitably banished into a strange and notoriously oppressive solitude. In our old church hymnal we used to sing with emotion a song by Novalis containing the line, "Be content to let others wander in their broad, resplendent, teeming streets.'’ These words might sound very appropriate as a slogan for theology; however, they would not be altogether honest, for who at bottom would not really like to be an individual in a greater crowd? Who, as long as he is not the oddest of odd fellows, would not like to have his work supported by the direct or at least indirect acknowledgment and participation of the general public, and understood by all men or at least as many as possible? As a rule, the theologian will have to put up with pursuing his subject in a certain isolation, not only in the so-called ''world," but also in the Church (and behind a "Chinese wall," as will soon enough be said).
