These are the three things which the Liberal wishes to keep in the Church. He knows that to do this the traditional forms of church life require great changes, but he wishes to preserve the institutional life of the Church as a valuable inheritance. To him it is clear that Christians who in one generation invented the theology, the sacraments, the thoughts, practices, and ordinances of the past, have the right in another generation to change these. The continuity of the Church is in membership, not in documents. But the Liberals fall into two groups. There is the left wing which expresses itself with clearness and decision, which is not afraid of recognizing that the Church in the past has often been wrong and has affirmed as fact what is really fiction. Those who belong to it are sometimes driven out by official pressure, and more often are compelled to yield to the practical necessities of ecclesiastical life, but their influence is greater than their numbers. The danger which would face the Church if they were allowed to have more prominence, is that their plainness of speech would lead to disruption. The danger is a real one, and the leaders of churches do right to fear it. Over against this is the right wing of Liberals. There is probably little difference in the matter of private opinion between them and the left wing, but they are more concerned with safeguarding the unity of the Church. They endeavour to do this by using the old phraseology with a new meaning, so that, for instance, members of this party feel justified in stating that they accept the creed, though they do not believe in it in the sense which was originally intended. This is technically called "reinterpreting," and by a sufficient amount of "reinterpreting" all the articles of the creed (or indeed anything else) can be given whatever meaning is desired. The statement that God created the heavens and the earth becomes in this way an affirmation of evolution; the Virgin Birth affirms the reality of Christ's human nature; and the Resurrection of the Flesh affirms the Immortality of the Soul. Performed with skill, this dialectical legerdemain is very soothing to a not unduly intelligent congregation and prevents any breach in the apparent continuity of the Church's belief. It also prevents any undue acrimoniousness of theological debate, for debate is difficult if words may be interpreted to mean the opposite of their historical significance. The danger is that the rising generation will refuse to accept this method, and that it will lead to deep and irretrievable intellectual confusion. This is what Father Knox clearly saw to be the intellectual sin of the "Foundationers."
