me," By all the
authority which belongs to him our Saviour _commands_ us to keep this
holy feast. And the first reason why we ought to "do this," is
because of its connection with the word of his command.

_The second reason why we ought to "do this"--is because of its
connection with the memory of his sufferings_.

We are taught this by the word _remembrance_, which our Saviour here
uses. He says, "This do in remembrance of me." This means in
remembrance of my sufferings for you. And _this_ is the most
important word used by him when he established this sacrament. It is
the governing word in the whole service. It is the word by which we
must be guided in trying to understand what our Lord meant to teach
us by all he did and said on this occasion.

You know how it is when we are trying to understand the music to
which a particular tune has been set. There is always one special
note in a tune, which is called the _key-note_. The leader of a
choir, when they are going to sing, will strike one of the keys of
the organ, or the melodeon they are using, so as to give to each
member of the choir the proper key-note of the piece of music they
are to sing. It is very important for them to have this key-note,
because they cannot have a proper understanding of what they are to
do without it. This holy sacrament of the Lord's Supper is like a
solemn song. And the key-note of the music to which the song is set
is this word--_remembrance_. It teaches us that the sacrament of the
Lord's Supper is a _memorial_ service. And, in going through the
music to which the song of this service has been set, every note that
we use must be a memorial note. And the language used by our blessed
Lord when he established this Supper, or sacrament, must be explained
in this way. When he broke the bread and gave it to his disciples,
saying--"This is my body, which is given for you: this do in
remembrance of me," he meant that we should understand him as
saying--"This is the _memorial_ of my body." And when he gave them
the cup, and said--"This is my blood of the New Testament," he meant
that we should understand him as saying--"This is the _memorial_ of
my blood." And we are sure that this was the meaning, for two
reasons.

One reason for believing this is that _this was the way in which
similar words had been used in the Jewish Passover, which Jesus and
his disciples were then keeping_.

In the Passover service, when the head of the family dist
