The Dedication of the Basilicas of Saints Peter and Paul
Already in the twelfth century there was being celebrated today the anniversary of the dedication of the basilicas of St Peter at the Vatican and St Paul in the Via Ostiense by Pope St Silvester and Pope St Siricius in the fourth century. More recently this commemoration has been extended to the whole Church, honouring the two greatest apostles of Christ just as the anniversary of the dedication of St Mary Major (5 August) celebrates the motherhood of the Virgin Mother of God.
