Belfast police prepare for Ulster Covenant centenary march The place of worship has been the scene of disorder at points during the summer after a band was accused of playing sectarian music outside it on July 12. The 2,000 marchers anticipated to pass the church have been ordered to play only sacred music while passing the venue. The Orange Order offered to play hymns as members passed the church but a residents' group from the surrounding area requested that no music be played. A legal attempt at Belfast High Court by a resident to overturn the commission's ruling failed. The commission said no supporters are allowed to accompany the parade on that section of the route while a protest planned by the residents' group has been limited to 150 participants. The commission has also placed the sacred music restriction on those bands that will pass St Matthew's Catholic Church in Newtownards Road close to Stormont. Politicians from across the political divide have appealed for calm at the event which is set to be one of the biggest loyal order parades seen in Belfast.
