The font was brought from Rome in 1912 by William Moir Bryce; it likely dates from the early Renaissance. The communion table of the New North Church stands at the east end of the north aisle while the communion table of New Greyfriars stands at the east end of the south aisle. The furnishings in the western part of the south aisle were moved from the St John's Chapel of Highland, Tolbooth, St John's. Pitch pine pews added to the nave during Henry F. Kerr's restoration of 1932-1938 were replaced by chairs in 1989.
