In the early Church, the faithful received the Eucharist in the form of
consecrated bread and wine. Saint Maximus explains that in the Old Law the
flesh of the sacrificial victim was shared with the people, but the blood of
the sacrifice was merely poured out on the altar. Under the New Law,
however, Jesus' blood was the drink shared by all of Christ's faithful. St.
Justin Martyr, an early Church father of the 2nd century, speaks of the
Eucharist as the same body and blood of Christ that was present in His
Incarnation. Source: Wikipedia
