John Harvard, for whom the university was named, was a preacher of the Gospel.
The university was founded to educate ministers and preachers of the Gospel.
Not just Harvard, but many top universities were like Berkeley too began as well until it was handed over only to have liberals overtake it.
At Harvard, Congregationalism gave way to Unitarianism, Unitarianism to Agnosticism, Agnosticism to utter madness ... and there we are today.
