S. Mary's Church was the only formal meeting place of these students, thus drawn together in the pursuit of knowledge from various parts of Europe. It was here that all University business, secular and religious, was transacted, till the building of the Divinity school and the Sheldonian theatre allowed the church to be reserved for sacred purposes. Then at last it ceased to be the scene of violent altercations between Heads of Houses or the stage where the Terræ Filius of the year should utter his scurrilous banalities.[24] But still every Sunday morning during term the great bell of S. Mary's rings out and summons the University to assemble in formal session there to hear a sermon. The bedels of the four faculties with their silver staves lead the way; and the Vice-chancellor is conducted to his throne, the preacher to his pulpit; the doctors of the several faculties in their rich robes follow and range themselves on either side of their official head; below them the proctors, representatives of the Masters of Arts, wearing the white hoods of their office, take their seats. The masters and bachelors fill the body of the church, the undergraduates are crowded into the galleries. We must not think of S. Mary's as merely a meeting-house for University business or as merely a parish church. For centuries it has been the centre of Christian Oxford; where each successive movement in English theology has been expounded and discussed. From the old stone pulpit, of which a fragment is fixed over the southern archway of the tower, Peter Martyr delivered his testimony and Cole sent Cranmer to the stake; from its nineteenth century successor, John Keble began the Oxford movement; Dr Pusey preached a sermon for which he was suspended, and Newman (vicar 1831) entered on the path to Rome. The church is mentioned in Domesday Book, and the north wall of the Lady Chapel, commonly known as Adam de Brome's Chapel because the tomb of the founder of Oriel is therein, may have been part of the church as it stood at the time of the Domesday survey. The tower and the spire date from the early fourteenth century. S. Mary's as we have it now is very much a Tudor building. When William of Wykeham built New College Chapel he set a fashion which soon converted Oxford into a city of pinnacles.[25] In the perpendicular style pinnacles were erected on Merton tower and transept, on All Souls' Chapel, on Magdalen Chapel, hall and tower; nearly a hundred pinnacles decorated the Schools and Library; the nave, aisles and chancel of S. Mary's received the same ornaments, and pinnacles in the same style were added to the clusters of the fourteenth century tower and spire. These were not high but observed a true proportion.
