After he had candidated at various Boston pulpits, in 1782 the Episcopalians at King's Chapel asked Freeman to officiate as their reader for six months. Founded in 1686, King's Chapel was the first Church of England parish in New England. The Rector, Henry Caner, a Loyalist, had been forced to leave in 1776 when the British troops evacuated Boston. After the departure of his assistant a few months later, the Chapel was closed for about a year. In 1777 the Chapel proprietors gave permission to the members of the Old South Church (Congregational), who had been displaced from their own meetinghouse by the British, to worship in King's Chapel. Because of anti-British sentiment, it was popularly known as Stone Chapel. Before long, the original congregation returned to the Chapel, and the two societies, one Episcopalian and one Congregational, shared the facilities until 1783 when the Old South Church congregation returned to its newly renovated building. Freeman was well liked at Stone Chapel. When his six months were concluded, at Easter 1783, the proprietors asked him to be Pastor of the Church.
