John Milton, The Ready and Easy Way to Establish a Free Commonwealth (1660)

[I]f we return to Kingship, and soon repent, as undoubtedly we shall, when we begin to find the old encroachments coming on by little and little upon our consciences, which must necessarily proceed from King and bishop united inseparably in one interest, we may be forced perhaps to fight over again all that we have fought, and spend over again all that we have spent, but are never like to attain thus far as we are now advanced to the recovery of our freedom, never to have it in possession as we now have it, never to be vouchsafed hereafter the like mercies and signal assistances from heaven in our cause, if by our ingrateful backsliding we make these fruitless; flying now to regal concessions from his divine condescensions and gracious answers to our once importuning prayers against the tyranny which we then groaned under: making vain and viler then dirt the blood of so many thousand faithful and valiant English men, who left us in this liberty, bought with their lives; losing by a strange after game of folly, all the battles we have won, together with all Scotland as to our conquest, hereby lost, which never any of our Kings could conquer, all the treasure we have spent, not that corruptible treasure only, but that far more precious of all our late miraculous deliverances; treading back again with lost labour all our happy steps in the progress of reformation; and most pitifully depriving our selves the instant fruition of that free government which we have so dearly purchased, a free Commonwealth, not only held by wisest men in all ages the noblest, the manliest, the equallest, the justest government, the most agreeable to all due liberty and proportioned equality, both human, civil, and Christian, most cherishing to virtue and true religion, but also (I may say it with greatest probability) plainly commended, or rather enjoined by our Saviour himself, to all Christians, not without remarkable disallowance, and the brand of gentilism upon kingship.
