Older manuscripts of the Roman Canon had ""qui tibi offerunt"" ("they offer it") without the preceding ""pro quibus tibi offerimus vel"" ("for them we offer you ... or"). Like Fortescue who also views the phrase as a later addition, Bradshaw and Johnson see as significant this addition of an originally alternative phrase that later became part of the fixed text: without it, the persons named were those who offered; with it, it was the priest who offered for them, a step towards considering irrelevant the actual presence of laypeople at the celebration of Mass.
