If anyone is interested, take a look at this short presentation on YouTube; http://www.youtube.com/watch?gl=GB&v=fLf4bezncGM.
This is where I spent my retreat (TLIG). It is run by members of the Coptic Orthodox Church and by volunteers (sometimes from other denominations). It is an "ecumenical" place in that it is open to groups from different denominations. It was founded by Bishop Thomas who gave us a wonderful talk about how he explained a particular aspect of the Eucharistic Mystery to a seven-year-old boy. Hopefully this will soon appear on YouTube.
