I think the Puritans would be amazed at the doings of their descendants: the latter following many of the former in the junking of special days like Pentecost and Trinity Sunday, but instead following the lead of their culture and doing all sorts of things to celebrate mums and dads even to the point of centring their preaching on mothers and fathers. To be sure, even the Puritans were not always consistent: they had their Guy Fawkes Day (Nov 5)! But all things in their proper place.
