What is the significance of the Episcopal Seal ("The Shield") and Flag?

This symbol, which you will see at virtually every Episcopal Church and website, is the official "logo" of ECUSA, and depicts our history.  It is red, white and blue...the colors of both the U.S. and England. The red Cross of St. George on a white field is symbolic of the Church of England. The blue field in the upper left corner is the Episcopal Church of the U.S.A. It features a Cross of St. Andrew, in recognition of the fact that the first American bishop was consecrated in Scotland.  This cross is made up of nine crosslets, which represent the nine dioceses that met in Philadelphia in 1789 to form the Protestant Episcopal Church of the U.S.A.
