"The danger of silent accumulations & encroachments by Ecclesiastical Bodies have not sufficiently engaged attention in the U. S. [...] But besides the danger of a direct mixture of Religion & civil Government, there is an evil which ought to be guarded agst in the indefinite accumulation of property from the capacity of holding it in perpetuity by ecclesiastical corporations. The power of all corporations, ought to be limited in this respect. The growing wealth acquired by them never fails to be a source of abuses. A warning on this subject is emphatically given in the example of the various Charitable establishments in G. B. the management of which has been lately scrutinized. The excessive wealth of ecclesiastical Corporations and the misuse of it in many Countries of Europe has long been a topic of complaint. In some of them the Church has amassed half perhaps the property of the nation. When the reformation took place, an event promoted if not caused, by that disordered state of things, how enormous were the treasures of religious societies, and how gross the corruptions engendered by them; so enormous & so gross as to produce in the Cabinets & Councils of the Protestant states a disregard, of all the pleas of the interested party drawn from the sanctions of the law, and the sacredness of property held in religious trust. The history of England during the period of the reformation offers a sufficient illustration for the present purpose. [...] Are there not already examples in the U. S. of ecclesiastical wealth equally beyond its object and the foresight of those who laid the foundation of it? In the U. S. there is a double motive for fixing limits in this case, because wealth may increase not only from additional gifts, but from exorbitant advances in the value of the primitive one. In grants of vacant lands, and of lands in the vicinity of growing towns & Cities the increase of value is often such as if foreseen, would essentially controul the liberality confirming them. The people of the U. S. owe their Independence & their liberty, to the wisdom of descrying in the minute tax of 3 pence on tea, the magnitude of the evil comprized in the precedent. Let them exert the same wisdom, in watching agst every evil lurking under plausible disguises, and growing up from small beginnings. Obsta principiis."
