Though each of the Twelve Apostles has his own Feast day, on this day they are commemorated together. Of the Twelve, only St John the Theologian died in peace; the rest met a martyr's end. Following are their individual feast days and the manner of their end.
Roman citizens could not be crucified: crucifixion was considered a shameful death unworthy of a citizen. For this reason the Apostle Paul was 'privileged' to be beheaded.
