in a catholic sense the term "saint" refers to any person in heaven—however, since the 10th century, the title "saint" is only given to persons who have been officially recognized by the church. in the days when the church of england was in union with the roman catholic church, recognition was in the form of canonization. those martys and confessors given the title traditionally, prior to the establishment of the canonization process or since the break with rome, are generally still considered both "saints" and "saints." the title "hero" is sometimes used as well, more often to refer to those saints who have lived and died since the time of the reformation. these days they tend to have commemoraitons.

i suppose josephine butler would be a modern-ish example. in the church of england she is celebrated with a lesser festival on 30 may. she is also represented in windows in liverpool's anglican cathedral, and st olave's church in the city of london.
