You may have seen this guy on a 2 dollar bill. 2nd President and 1st Vice President. Writing in a private letter to his wife, which he likely thought others would never see...

I confess I am not fond of the Presbyterian Meetings in this Town. I had rather go to our Church. We have better sermons, better prayers, better speakers, softer, sweeter musick, and genteeler company. 

And I must confess, that the Episcopal Church is quite as disagreeable to my taste as the Presbyterian. They are both Slaves to the Domination of the Priesthood. I like the Congregational way best - next to that, the Independent.
