Bishop of Woolwich Michael Ipgrave and a group of young people started a four-day walk 'beating the bounds' of the Woolwich Episcopal Area at Southwark Cathedral on Tuesday morning.
Southwark's area bishop and eight young Anglicans aged 11-25 years set out early on Rogation Tuesday after joining the cathedral canons for morning prayer. Rogation-tide is the traditional time for walking parish and farm boundaries.
The Woolwich Area Youth Pilgrimage walk is following the 46-mile boundary of the Woolwich Episcopal Area which covers the boroughs of Southwark, Lewisham and Greenwich.
Young members of local churches are being invited to join the bishop for different sections of the walk.
The first day's walk followed the Thames Path as far as the Woolwich Ferry and covered the northern edge of all three boroughs. At one point during the day 80 people joined the group.
At the cathedral the walk started in the covered Lancelot's Link passageway where the walkers played hopscotch using the paving stones which carry the names of parishes around the diocese.
The return to the cathedral will be on Friday when the party which will grow over the days approaches the Elephant & Castle from Walworth Road.
The walkers are due to meet young Muslims at the Rockingham Community Centre in the afternoon. Afterwards the young people from both faiths are planning to walk together to Borough High Street as an act of peace.
The Anglican Diocese of Southwark is divided into three episcopal areas, each with an area bishop.
