Eucharist is a sacrament which is "the permanent gift of the Body and Blood of Christ under the appearances of bread and wine which nourishes and fortifies those on a pilgrimage to God." (p.90). The formula used at the Mass in the Eucharistic Prayer, "Take this, all of you, and eat of it, for this is my Body, which will be given up for you. . . . Take this, all of you, and drink from it, for this is the chalice of my Blood, the Blood of the new and eternal covenant, which will be poured out for you and for many for the forgiveness of sins. Do this in memory of me."
