"Did Miles Standish write, "Let vs then make merrie and feste like untoe ye feaste of Tabernacles"?"

No. The Puritans did not make merry. These are the same people who got booted out of England for abolishing Christmas, amongst other outrages against the national character. They claimed to have gone to America to seek religious freedom, but while in control in England they were the greatest religious bigots of them all, jailing all and sundry who didn't follow their narrow ways.

This is not to mention the excursions of that arch-Puritan, Oliver Cromwell, amongst the Scots and Irish -- his name is a curse to them to this day. Add to that any number of vandalized cathedrals and churches. Fittingly, Oliver Cromwell was a distant relation of that earlier curse of England, Thomas Cromwell, who also specialized in looting and damaging churches. No wonder that upon the restoration of the monarchy they dug Oliver out of his tomb in Westminster Abbey, stuck him up on the bar of the Red Lion in Holborne for a while, and then hung him up and chopped him up at the gallows at Tyburn before burying him beneath it. ( His head was visible for some years.)

I'm sure that when the Puritans gave thanks they did so with very long-winded prayers, and dour faces, and a thought that all the blessings in the Bible were for themselves and all the curses for everyone else.

Read Samuel Pepys's description of London in the time of the Puritans in his "Diary", the uncensored version of which is at last available.
