1.By showing that it is possible to change one substance into another;
2. By showing that Christ did change the substance of bread and wine into the substance of His body and
blood;
3. By showing that He gave this power also to His Apostles and to the priests of His Church.
Q. 878. How do we know that it is possible to change one substance into another?
A. We know that it is possible to change one substance into another, because:
1.God changed water into blood during the plagues of Egypt.
2. Christ changed water into wine at the marriage of Cana.
3.Our own food is daily changed into the substance of our flesh and blood; and what God does gradually,
He can also do instantly by an act of His will.
Q. 879. Are these changes exactly the same as the changes that take place in the Holy Eucharist?

changes the appearance also is changed, but in the Holy Eucharist only the substance is changed while the
appearance remains the same.

2. From the words by which He instituted the Holy Eucharist;
3. From the constant use of the Holy Eucharist in the Church since the time of the Apostles;
4. From the impossibility of denying the Real Presence in the Holy Eucharist, without likewise denying all
that Christ has taught and done; for we have stronger proofs for the Holy Eucharist than for any other
Christian truth.

Q. 882. How do we know that under the appearance of bread we receive also Christ's blood; and under
the appearance of wine we receive also Christ's body?
A. We know that under the appearance of bread we receive also Christ's blood, and under the appearance of
wine we receive also Christ's body; because in the Holy Eucharist we receive the living body of Our Lord, and a
living body cannot exist without blood, nor can living blood exist without a body.
Q. 883. Is Jesus Christ present whole and entire in the smallest portion of the Holy Eucharist, under the
form of either bread or wine?
A. Jesus Christ is present whole and entire in the smallest portion of the Holy Eucharist under the form of either
bread or wine; for His body in the Eucharist is in a glorified state, and as it partakes of the character of a spiritual
substance, it requires no definite size or shape.

Q. 888. Are there not, then, as many bodies of Christ as there are tabernacles in the world, or as there
are Masses being said at the same time?
A. There are not as many bodies of Christ as there are tabernacles in the world, or as there are Masses being said
at
the same time; but only one body of Christ, which is everywhere present
whole and entire in the Holy Eucharist, as God is everywhere present,
while He is but one God.

A. The Consecration in the Mass takes place immediately before the elevation of the Host and Chalice, which are
raised above the head of the priest that the people may adore Our Lord who has just come to the altar at the
words of Consecration.
