These are the lessons of practical piety, which bring the mind into a situation to worship acceptably, and under the influence of which, men but little instructed in human learning, are often enabled to counsel the wise of this world in the things that lead to their peace. But if these things are all to be changed: if in place of this simple, practical religion, our places of worship are to be converted into theatres for metaphysical disquisitions, and the discussion of questions more curious than useful; and we are to be instructed in the unprofitable controversies which have so long perplexed and disturbed the christian world: if faith is no longer a christian principle, and the revelations of the scriptures rejected when not to be arrived at by the analogy of reason, then indeed must the Quaker ministry be constituted anew, and even your own labours cease. The old and unchanged servants can take no part or portion in the new order of things; and it cannot be expected that the disciples of the new school will take for a master to lead them to the truth by analogous reasoning, one, who has yet to be taught what reason really is. LETTER IX. Your assertion that "you cannot believe what you do not understand," is often quoted by your followers, as a proof of your having emancipated yourself from the thraldom of tradition, and risen superior to those prejudices, which early education, and the authority of antiquity have fastened on the minds of men; and yet when we examine and compare this assertion with the doctrines you inculcate, it appears evident that you have not a correct idea of the meaning of your favourite maxim. This understanding can only be arrived at by the natural faculties of perception, judgment, and reasoning, and as the truth of the especial revelations of which you speak, are propositions which cannot be demonstrated by the use of these faculties; they must, if assented to, be purely matters of faith, arising from our belief in the general truth of the christian dispensation. There is a clear distinction between things which are according to, above, and contrary to, reason. The first are propositions, the truth of which may be discovered by the use of the ideas we have acquired from sensation and reflection. The second are propositions whose truth cannot be investigated by these means: and the third, such as are inconsistent and irreconcileable to our clear and distinct ideas.
