The money powers prey upon the nation in times of peace and conspire against it in times of adversity. It is more despotic than a monarchy, more insolent than autocracy, and more selfish than bureaucracy. It denounces as public enemies, all who question its methods or throw light upon its crimes. I have two great enemies, the Southern Army in front of me and the Bankers in the rear. Of the two, the one at my rear is my greatest foe.. corporations have been enthroned and an era of corruption in high places will follow, and the money powers of the country will endeavor to prolong its reign by working upon the prejudices of the people until the wealth is aggregated in the hands of a few, and the Republic is destroyed.

And of course, there is Gettysburg's address,
"that this nation, under God, shall have a new birth of freedom—and that government: of the people"
According to the Wikipedia, this phrase originated in Theordore Parker's sermons which said, 'Democracy is direct self-government, over all the people, for all the people, by all the people" which is certainly more participatory democracy than I am sure Lincoln had in mind.
“The Government should create, issue, and circulate all the currency and credits needed to satisfy the spending power of the Government and the buying power of consumers. By the adoption of these principles, the taxpayers will be saved immense sums of interest. Money will cease to be master and become the servant of humanity.” - Abraham Lincoln
