The Westminster Confession, of post Civil War England in the late 1600s, pushes Trinitarianism but not because of true scripture but because of reliance on writings of Trinitarians such as the post-200 AD reputed ‘church fathers’, church councils such as Nicea and Chalcedon, and reformers such as Calvin. This is ironic since that same Westminster Confession inconsistently also pushes sola scriptura, insisting essential doctrines must only be based on canonised (by them) scriptures.
