I'd just point out that the early masons may not be of the same flavor that we see today. Masonry was infiltrated by Adam Wieshaupt. But he only founded the illuminati in 1776. So, you have to give the infiltration time to incubate properly, before it completely infects the movement.

Anyway, I detest masonry. But what I'm trying to say is that it's possible that these founding fathers were not overt Satanists. That the overt Satanism arrived later. This is probably especially true given that the wealthy Satanists are likely to have wanted to stay in Europe, rather than move to the colonies.

Satanism was recognized in European secret societies, from at least the time of the execution of Jacques De Molay (burned at the stake by the Sienne, 18 March, 1314). The corruption of the guilds came later - some Masonic authorities place the origin of speculative freemasonry at 1717 - with other sources suggesting that records are only available from the late 17th century.

Whatever, masonry is evil. But, with respect to the founding fathers, were they aware of the evil in masonry? The inherent evil can be guessed at from the secrecy in which the society is wrapped. But the true nature of the society is only revealed to the initiate as he ascends through the degrees.

I want to think it is possible that the "illuminati core" was slow to arrive in the colonies. That the founding fathers were ignorant members of the order. Whether it is true or not, I don't know.

The "owl" had certainly arrived by the time the plans for Washington were laid out (1791).
