At age 14, Brown was baptized at Hudson, New York. He attended Madison College (now Colgate University), graduating at the top of his class in 1823.
He was ordained at Buffalo, New York, in 1824, and the next year moved to Providence, Rhode Island to assist Dr. Gano, pastor of the First Baptist Church there. In 1827, he became pastor of the Baptist church in Malden, Massachusetts. In 1829, he moved to Exeter, New Hampshire, where he had accepted the pastorate of the Baptist church.
In 1838, he became associate professor of theology and pastoral relations at the New Hampton Literary and Theological Institution, New Hampton, New Hampshire. In 1845, he became pastor of the Baptist church in Lexington, Virginia.

While in Exeter, Brown edited his Encyclopædia of Religious Knowledge. It was published in Brattleborough, New Hampshire, in 1835, then republished in England. His other works include:
Brown helped write the New Hampshire Confession of Faith in 1833, a more moderate expression of the Calvinistic Baptist beliefs that existed at the time, and was widely accepted in the northern United States.
At the time of his death, Brown was preparing a history of the Baptists.
