The Pope says Mass in a largely empty stadium on a visit to Georgia after the majority Orthodox Christian Church asks followers to stay away.

…The Orthodox patriarchate said on its website: “As long as there are dogmatic differences between our churches, Orthodox believers will not participate in their prayers”.

One Georgian priest told AP it was a protest against Catholic attempts to convert Orthodox Christians.

“Can you imagine how it would be if a Sunni [Muslim] preacher came to Shia [Muslim] Iran and conducted prayers in a stadium or somewhere else?” Father David Klividze asked. “Such a thing could not be.”
