Commonplace: Catholicism's Organic Identity
We Catholics do not quarrel with the methods of the religious historian, so long as he keeps within his proper limits, within the limits of historical data and proved historical fact, and so long as he does not claim in his classification of religious types to pass decisive judgment upon the essential nature of the religious structure which he has under examination. We Catholics acknowledge readily, without any shame, nay with pride, that Catholicism cannot be identified simply and wholly with primitive Christianity, nor even with the Gospel of Christ, in the same way that the great oak cannot be identified with the tiny acorn. There is no mechanical identity, but an organic identity. And we go further and say that thousands of years hence Catholicism will probably be even richer, more luxuriant, more manifold in dogma, morals, law and worship than the Catholicism of the present day. A religious historian of the fifth millennium A. D. will without difficulty discover in Catholicism conceptions and forms and practices which derive from India, China and Japan, and he will have to recognise a far more obvious ‘‘complex of opposites.” It is quite true, Catholicism is a union of contraries. But contraries are not contradictories. Wherever there is life, there you must have conflict and contrary. Even in purely biblical Christianity, and especially in Old Testament religion, these conflicts and contraries may be observed. For only so is there growth and the continual emergence of new forms. The Gospel of Christ would have been no living gospel, and the seed which He scattered no living seed, if it had remained ever the tiny seed of A. D. 33, and had not struck root, and had not assimilated foreign matter, and had not by the help of this foreign matter grown up into a tree, so that the birds of the air dwell in its branches.
