The bread that you see on the altar is the Body of Christ as soon as it is sanctified by God's word. The chalice, or better what is contained in the chalice, is the Blood of Christ as soon as it is sanctified by God's word
Saint AugustineIf I am given a formula, and I am ignorant of its meaning, it cannot teach me anything, but if I already know it what does the formula teach me?
Saint Augustine...But we enjoyed playing games and were punished for them by men who played games themselves. However, grown-up games are known as 'business' and even though boys' games are much the same, they are punished for them by their elders. No one pities either the boys or the men, though surely we deserve pity, for I cannot believe that a good judge would approve of the beatings I received as a boy on the ground that my games delayed my progress in studying subjects which would enable me to play a less creditable game later in life.
