Sage was born in that part of the Town of Chatham which was later separated as the Town of Portland, in Middlesex County, Connecticut. He received his early education from a private tutor and graduated from Yale College in 1778. He studied medicine, and commenced practice in Easthampton, Suffolk County, New York in 1784. He moved to Sag Harbor about 1801.
Sage was elected as a Democratic-Republican to the 11th, 12th and 13th United States Congresses, holding office from March 4, 1809 to March 3, 1815. Credentials of his election to the 16th United States Congress were issued by the Secretary of State of New York but Sage did not claim or take the seat. James Guyon, Jr., successfully contested Sage's election and was seated on January 14, 1820.
Sage resumed the practice of medicine at Sag Harbor and was a delegate to the New York State Constitutional Convention of 1821. He died at Sag Harbor and was originally buried at the Old Burying Ground, but later re-interred in Oakland Cemetery.
