Mass according to Divine Worship (the Ordinariate Missal) is offered twice a week at Holy Rood. During the University vacation, the choir does not sing, and Mass is offered at the Blessed Sacrament altar. The usual pattern of services is as follows:
Saturdays at 5pm (which fulfills the Sunday obligation), and
Thursdays at 6.30pm (followed by Exposition of the Blessed Sacrament and Confessions, 7-8pm).
