"A doctrine is something that pins you down to a given mode of conduct and dozens of situations which you cannot foresee, which is a great mistake in principle. When the word 'containment' was used in my 'X' article, it was used with relation to a certain situation then prevailing, and as a response to it."

Sacred Scripture, since it has no science above itself, can dispute with one who denies its principles only if the opponent admits some at least of the truths obtained through divine revelation; thus we can argue with heretics from texts in Holy Writ, and against those who deny one article of faith we can argue from another. If our opponent believes nothing of divine revelation, there is no longer any means of proving the articles of faith by reasoning, but only of answering his objections - if he has any - against faith.
