This year, one of the changes is that the 2008 year Western tradition (well give or take a bit) of celebrating St Luke in Red has in this 2009th year been changed to White. So today you can wear Green (the Sunday), White (the suggested colour in the lectionary), or Red (as a liturgical rebel like me will do – following the 2008 or so years of Western tradition!). Matthew and Mark’s colours have similarly been changed in the NZ Lectionary from Red to White.
