The Jews in general
The Jews, as a people, have been alleged by Christians to have had a special responsibility for this crime and to have been cursed by God for it. (See Supersessionism)
Until the middle of the 20th century most Christian churches included references to deicide in their hymns and liturgy. Many still do. The following, for example, is a verse from a hymn used in Protestant churches to call upon God to convert the Jews to Christianity:
Though the Blood betrayed and spilt,
On the race entailed a doom,
Let its virtue cleanse the guilt,
Melt the hardness, chase the gloom;
Lift the veil from off their heart,
Make them Israelites indeed,
Meet once more for lot and part
With Thy household's genuine seed.[1]
