Your own doctrines also derive from those folks. They were not heretics.
One of America's foremost religious analysts was John Leland (who wrote, with James Madison, the First Amendment).
He differed with most Protestants of his time on the question of SUNDAY SCHOOL and congregational missionaries. His views were essentially identical to that of the Orthodox and pretty doggone similar to the RCC.
I think Sunday School is great, and if a congregation wants to sponsor a foreign mission that's great too. So, I differ with an ancestor who helped found an entire religious movement (where I remain a member) ~ amazing isn't it.
Just because someone has heretical beliefs doesn’t mean they’re all bad.
On the contrary, there have been many great people who have held heretical beliefs.
