The Holy Spirit did not go into such detail about the Pharisees in the New Testament just so we could understand a group unique to the first century. Pharisaism is a poisonous weed that grows in every garden of orthodox religion. Pharisaism is every bit the threat to the orthodox today that it was then.
What I have said respecting and against religion, I mean strictly to apply to the slaveholding religion of this land, and with no possible reference to Christianity proper; for, between the Christianity of this land, and the Christianity of Christ, I recognize the widest possible difference—so wide, that to receive the one as good, pure, and holy, is of necessity to reject the other as bad, corrupt, and wicked. To be the friend of the one, is of necessity to be the enemy of the other. I love the pure, peaceable, and impartial Christianity of Christ: I therefore hate the corrupt, slaveholding, women-whipping, cradle-plundering, partial and hypocritical Christianity of this land. Indeed, I can see no reason, but the most deceitful one, for calling the religion of this land Christianity.
