There is a view, not universally accepted, that parts of the present building, and, in particular, the font, predate the Norman conquest of England. The font has interlacing ornament of a style originating in Northumbria in the early days of English Christianity. The architectural historians, Jennifer Sherwood and Nikolaus Pevsner describe the font as Norman, while Liam Tiller comments, "It is surprising that such a high quality font should be found in such a small rural chapel", and suggests that it may have been brought to Berrick from a larger church, perhaps Chalgrove, at a later date. Also, Moreau observes that Berrick church is not included in the Taylors' comprehensive work on Anglo-Saxon architecture.
