A church was established on this site, at the centre of the old
walled city, in
Anglo-Saxon times; records of 1086 note the church as previously belonging to an estate held by
Aubrey de Coucy, likely
Iffley, and the parish including part of
Littlemore. In the early days of
Oxford University, the church was adopted as the first building of the university,
congregation met there from at least 1252, and the upper storey housed books bequeathed by
Thomas Cobham,
Bishop of Worcester, which formed the first university library. Early
provosts of the college were inducted into their stall in the church, and until 1642 fellows were required to attend services on Sundays and holy days. was repugnant to
William Laud,
Archbishop of Canterbury, who in the 1630s initiated the erecting of a separate building for these ceremonies. This project was cut short by the fall of Laud and the outbreak of the
English Civil War, but after the Restoration, it was revived and carried through by
John Fell, Dean of
Christ Church, who commissioned
Christopher Wren to erect what became the
Sheldonian Theatre. Thereafter, the church was reserved for religious worship only. During his time in Oxford,
John Wesley often attended the university sermon, and the "Almost Christian" sermon on 25 July 1741. Following his denunciation of the spiritual apathy and sloth of the senior members of the university in his sermon "Scriptural Christianity" on 24 August 1744, he was never asked to preach there again — "I preached, I suppose, the last time at St Mary's", he wrote in his journal, "Be it so; I have fully delivered my soul." In 1828,
John Henry Newman became vicar and his sermons became popular with undergraduates. From the present pulpit
John Keble preached
the assize sermon of 14 July 1833, which is traditionally considered to have started the
Oxford Movement, an attempt to revive
catholic spirituality in the church and university. The influence of the movement spread and affected the practice and spirituality of the Church of England. By 1843, Newman became disillusioned with
Anglicanism and resigned from St Mary's, later joining the
Roman Catholic Church. ==Architecture==
