Russian Easter bread is a delicious treat that I highly recommend. It is made with saffron for crying out loud! Written on top in frosted letters is often “XB”. What does this mean? This is an abbreviation of Христос воскрес (Christ is risen). Notice that Christ is spelled in an ‘X’. This comes from the Greek letter ‘chi’ as Χριστός is ‘Christ’ in Greek. So contrary to the beliefs of many, ‘xmas’ is not an attempt at making Christmas secular. Instead it is the original abbreviation for Christ dating back to the 16th century. Other words that date back just as far are ‘Xtian’ and ‘Xtianity’.
