Peters (St) Day
Peter's (St.) Day (June 29) is a festival observed in the Roman Catholic Church. Its origin has been traced back to the 3d century. In 348 Prudentius mentions that the pope celebrated the Holy Communion in both St. Peter's and St. Paul's churches at Rome on this festival, which in the 6th century was observed at Constantinople, and was kept, until the Reformation, associated with the name of St. Paul, whose conversion was not generally commemorated on Jan. 25 until the 12th century. Cathedra Sancti Petri is a commemoration virtually of SS. Peter and Paul, but its title is the Chair of St. Peter, wherein he first sat at Rome, January 18. On February 22 his chair at Antioch is commemorated.
