Speaking of the Anglican Covenant ...

... thanks to Episcopal Cafe for this reflection by Immanuel Kant on the efficacy of Religious Covenents:

Immanuel Kant (1704-1824) on Religious Covenants.
From "What is Enlightenment?" (1784)

"But should not a society of clergymen, for example an ecclesiastical synod or a venerable presbytery (as the Dutch call it), be entitled to commit itself by oath to a certain unalterable set of doctrines, in order to secure for a time a constant guardianship over each of its members, and through them over the people?

I reply that this is quite impossible. A contract of this kind, concluded with a view to preventing all further enlightenment of mankind for ever, is absolutely null and void, even it is is ratified by the supreme power, by Imperial Diets and the most solemn peace treaties.

One age cannot enter into an alliance on oath to put the next age in a position where it would be impossible for it to extend and correct its knowledge, particularly on such important matters, or to make any progress whatsoever in enlightenment. This would be a crime against human nature, whose original destiny lies precisely in such progress. Later generations are thus perfectly entitled to dismiss these agreements as unauthorized and criminal."
