St Vincent de Paul Society members from Wales have been performing the play, based on Brian Griffiths' The Road to Calvary, since 1984.
This year, the play comes to Southwark for the first time.
It is a vivid and dramatic account of the last 12 hours of Jesus' life.
There is no interval and the performance lasts 90 minutes.
