So God the Holy Ghost, the Spirit of Truth, the Comforter to come, to complete the happiness of the human race, personates that spirit of free communication of knowledge which should be found in the Church, the theatre, not of any superstition or dramatic ceremony, but of the freedom of the human mind, and all its emanations of free enquiry, free discussion, mutual instruction, which are the necessary elements of brotherly love and peace, in the proving of all things and holding fast that which is good. And thus I prove the truth of the doctrine of the Trinity. This, Sir, is a true picture or effigies of the moral Trinity of the Christian Church, which you will find to be a key to every mysterious sentence of the Bible; and I ask you seriously, as between man and man, is any thing of this kind known or practised in the present Church? Are not the ministers of that Church afraid of every new discovery in science? Have they not, as far as they could, persecuted every man who has attempted to publish any criticism, enquiry, or objection to their mysterious subjects? History says--Yes. And I say that they have known nothing of the subject for themselves, and that they have dreaded all knowledge of, all enquiry into, the subject. Will their pride let them learn of me? Well may I say:--"Come unto me, all that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me: for I am meek and lowly of heart: and ye shall find rest unto your souls. For my yoke is easy and my burden is light." That is the language of the personated Logos, or Principle of Reason, addressed to the present state of British mind, as it was formerly addressed to the general state of the human mind. The doctrine of the transubstantiation of bread and wine, as the elements of the Sacrament of the Lord's Supper, into the real body and blood of Christ, has been another stumbling-block in the Church. On this head, our law-established Church has dissented from its former self, which when I mentioned on my last jury trial, the Judge, Sir Allan Park, called it a vilifying of the Church. I knew better; but saw that the Judge was not a man to be reasoned with, and so I did not press the subject: but through this letter and your name, Sir, I desire to teach him how it has been done. Transubstantiation is no stumbling-block to my mind. The twenty-eighth article of the Church says on this subject:--"Transubstantiation (or the change of the substance of bread and wine) in the Supper of the Lord, cannot be proved by Holy Writ; but is repugnant to the plain words of Scripture, overthroweth the nature of a Sacrament, and hath given occasion to many superstitions. The body of Christ is given, taken, and eaten in the Supper, only after an heavenly and spiritual manner; and the mean whereby the body of Christ is received and eaten in the Supper, is Faith."
