The Assembly of Christian Believers meeting in the Name and to the Person of the Lord Jesus Christ, now commonly known as the New Hampshire Avenue Gospel Chapel, was first established in Washington, D.C. on April 30, 1916, in the home of Mr.& Mrs. Frank Ruebsam, at 5224 Illinois Avenue, NW, Washington, D.C.

Later, though the precise dates are not known, the Assembly moved several times. After the home of the Ruebsams, the Assembly met at the home of Mr. & Mrs. Nicholas Fillmann, at Twining City, NW, Washington, D.C. Thereafter, the Assembly moved (due to growth needs) and met in rented premises at 1420 H Street, NE, Washington, D.C. Thence, the Assembly met in a rented building at 245 15th Street, SE, Washington, D.C.

In 1938, the Assembly constructed its own building at 5720 South Dakota Avenue, NE, Washington, D.C. The Assembly incorporated itself on February 1, 1938, as Christians Gathered unto the Name of the Lord Jesus Christ under the laws of the District of Columbia. The Assembly was then known as the Chillum Heights Gospel Chapel.

As the Assembly grew and the communicant members followed the suburban outflow, it sold its Chillum Heights building, whilst the current building at 12608 New Hampshire Avenue, Silver Spring, Maryland, was under construction. During this interregnum, the Assembly held its meetings at the Seventh Day Adventist church building at Riggs Road, Adelphi, Maryland.

Construction having been completed, the Assembly moved into its new building at New Hampshire Avenue, Silver Spring, and held its first meetings on May 24, 1964. The event was covered by the Washington Post and the meetings were conducted by Guest Speakers Alfred P. Gibbs of Waynesboro, Georgia, and George M. Landis of Fayetteville, Pennsylvania. The Post reported that the building cost around $90,000 and contains a nave seating 200, a social hall with kitchen, six classrooms and church office. The baptistery at the rear of the chancel has a blue glass partition which is reflected in the blue pew cushions and a blue glass partition separating the nave from the foyer. The ceiling is supported by laminated wood arches.

Chillum Heights Gospel Chapel then became known as the New Hampshire Avenue Gospel Chapel. The Assembly re-incorporated itself in the State of Maryland on March 27th, 1981.
