It is a favourite threat of the priesthood to any inquiring spirit: "If you give up Christianity you give up all certainty; rationalism speaks with no certain sound; no two rationalists think alike; the word rationalism covers everything outside Christianity, from Unitarianism to the blankest atheism;" and many a timid soul starts back, feeling that if this is true it is better to rest where it is, and inquire no more. To such--and I meet many such--I would suggest one very simple thought: does "Christianity" give any more certainty than rationalism? Just try asking your mentor, "_whose_ Christianity am I to accept?" He will stammer out, "Oh, the teaching of the Bible, of course." But persevere: "As explained by whom? for all claim to found their Christianity on the Bible: am I to accept the defined logical Christianity of Pius IX., defiant of history, of science, of common sense, or shall I sit under Spurgeon, the denunciator, and flee from the scarlet woman and the cup of her fascinations: shall I believe the Christianity of Dean Stanley, instinct with his own gracious, kindly spirit, cultured and polished, pure and loving, or shall I fly from it as a sweet but insidious poison, as I am exhorted to do by Dr. Pusey, who rails at his 'variegated language which destroys all definiteness of meaning.' For pity's sake, good father, label for me the various bottles of Christian medicine, that I may know which is healing to the soul, which may be touched with caution, as for external application, and which are rank poison." All the priest will find to answer is, that "under sad diversities of opinion there are certain saving truths common to all forms of Christianity," but he will object to particularise what they are, and at this stage will wax angry and refuse to argue with anyone who shows a spirit so carping and so conceited. There is the same diversity in rationalism as in Christianity, because human nature is diverse, but there is also one bond between all freethinkers, one "great saving truth" of rationalism, one article of faith, and that is, that "free inquiry is the right of every human soul;" diverse in much, we all agree in this, and so strong is this bond that we readily welcome any thinker, however we disagree with his thoughts, provided only that he think them honestly and allow to all the liberty of holding their own opinions also. We are bound together in one common hatred of Dogmatism, one common love of liberty of thought and speech.
