A remarkable alteration now took place, doubtless caused by another view being taken of the meaning of the feast. When the words _Cathedra Petri_ were no longer taken as referring to the bestowal of the Primacy or the episcopal and teaching office in general, but as referring to some definite episcopal See, then the question was asked, Is Antioch meant or Rome? For although the official lists reckon Evodius, and not St Peter, as first bishop of Antioch, still there were writers of antiquity, such as Origen, who represent St Peter’s residence in Antioch (Gal. ii. 11) as his Antiochene episcopate. This view led to the division of the feast into a Roman and an Antiochene Feast of St Peter’s Chair; for reasons which are unknown, the 18th January was chosen for the former, while the latter continued to be celebrated on the 22nd February. The martyrology of the Venerable Bede marks the date at which this division of the feast came into existence. In the original recension, given by the Bollandists, the feast of the 18th January does not appear, but the feast of the 22nd February has the note attached, “At Antioch.” It is possible that Bede considered the feast commemorated the commencement of a particular episcopate, and since, according to his idea, the Antiochene episcopate of St Peter preceded his Roman, and Antioch must have been the first See occupied by the apostle, he added the words, “At Antioch, where the disciples were first named Christians.” The separation is complete in Ado and Usuardus, and appears in the oldest editions of the _Hieronymianum_, and, in defect of further information, the compiler of this document may be regarded as the originator of the separation.[659] There thus arose a threefold practice—either both feasts were kept, or neither, or that of the 22nd February; the last was the case in only a few dioceses. The Cologne Calendar of the fourteenth century had only one feast, but the more ancient calendar belonging to the ninth century had both.[660]
