According to Canon Law (Can. 944 §1,2) "Wherever in the judgment of the diocesan Bishop it can be done, a procession through the streets is to be held, especially on the solemnity of the Body and Blood of Christ, as a public witness of veneration of the Blessed Eucharist. It is for the diocesan Bishop to establish such regulations about processions as will provide participation in them and for their being carried out in a dignified manner." Above, the Procession departs from Blackfriars priory church, the second 'station' of the Oxford Procession. This photo is from the 2008 Procession, when Bishop William Kenney CP took part. This year's Procession is on Sunday 6 June when Corpus Christi is celebrated in England & Wales.
