This large meeting room directly behind the sanctuary is dedicated to Adoniram Judson. A native of Malden, Rev. Judson (1788-1850) was the first American Baptist Missionary to Burma and translated the Bible into Burmese. The dome atop the elevated platform was designed for effective sound production and has been the venue for several musical and cultural performances.
On Sundays, the Chapel becomes the fellowship area of the congregation during coffee hour after the worship service.
Arched glass wall on the second and third floors reveal the church school rooms. The ground floor on this side leads to the Church parlor and the stairs going down to the social hall.
The entrance to the Chapel is a sliding door and serves to divide the Sanctuary and the Chapel. Once closed, a Church school gathering can be held simultaneously without distracting the on-going worship service in the sanctuary.
The banners hanging in Judson Chapel have been made by various group of people in the congregation.
