There are several places in our daily prayer services where we pray for the restoration of the Temple and the resumption of its rituals, including the rituals of sacrifice. Most types of offerings could be eaten. Certain types were eaten by the kohanim only, or by a specific kohein. Other types were eaten by the person offering the sacrifice and his family. The types of offerings and who was permitted to eat them will be discussed further below .
Animal sacrifice is no more cruel than slaughtering animals for food.
In fact, the procedure for slaughtering livestock for sacrificial purposes is the same as the procedure used for slaughtering animals for food, a procedure that is designed to be as quick and painless as possible. See Shechitah . Judaism is very concerned about the proper treatment of animals , and would never advocate a cruel procedure for animal sacrifice. Forgiveness is obtained through repentance , prayer and good deeds. In Jewish practice, prayer has taken the place of sacrifices.
