The Greek hagios means reverend, holy, set apart for God. Saint John means Holy John. Every Christian is a saint (small s), someone made holy directly by the authority of heaven, whereas a Saint (capital S) is someone recognized by local tradition or authorities on earth. Until 993 AD inclusion in a list of Saints was not formalized. Then the western or Roman Catholic Church began formalizing the official list with the canonization of Ulrich of Augsburg. As an interesting aside Saint Patrick is so-called because of popularity and has never been formally canonized as a saint. The Eastern Orthodox Church continues to acknowledge Saints recognized by local tradition in most cases. Many Protestants also use the term for famous saints to varying degrees. All Christians are saints, not by their own righteousness, but because God has made them holy.
