The story of this parish began in the heart and mind of the Rt Rev J Gillespie Armstrong. Bishop Armstrong talked often to the clergy of the diocese about the need for a parish in Blue Bell. On June 10, 1963, Bishop Armstrong appointed a three-man committee to move on establishing a church. The mission would be a joint venture of St Thomas', Whitemarsh; Trinity, Ambler; and Church of the Messiah, Gwynedd. The Rev Robert B Cook, as assisting priest at St Thomas', was appointed vicar of the mission.
On June 19th, 1963, the Rev Robert Wainwright of the Norristown area convocation led an organizational meeting, where several names were considered for the new mission. It was finally agreed that the name of the parish would be St Dunstan's, in honor of the most significant Abbot of Glastonbury and the 23rd Archbishop of Canterbury.
The mission began meeting over a three-room garage owned by Mr and Mrs John Black Jr. and was chartered on September 15th, 1963. In November of that same year, the diocese took title to a 9.5 acre property that had once been a sheep farm. Canterbury Acres was given to the diocese for the mission of St Dunstan's by Mrs Clarence Doan, a member of Church of the Messiah, Gwynedd.
The Bishop's Committee interviewed several architects and in 1964 Mr Harold Waggoner of Philadelphia was engaged to make preliminary drawings of the new church, which was built in 1965.
In our over 50-year history, the parishioners of St Dunstan's have served God by serving the greater Blue Bell area with love and dedication by supporting the Ambler Food Cupboard, Episcopal Community Services and Heifer Fund International.
In 2008 an outdoor labyrinth was built and dedicated, and a new playground was installed in 2010.
