AE 959, 960 - the second commandment

AE 959 [4]

. . . the quality of God or the Lord
is everything that is from Him
by which He is worshiped.

AE 960 [14-15]

Since "the name of God" means
that which is from God and which is God,
and this is called the Divine truth,
and with us the Word,
this must not be profaned,
because it is in itself Divine and most holy;
and it is profaned when its holiness is denied,
which is done when it is despised, rejected,
and treated contemptuously.
When this is done
heaven is closed and man is left to hell.
For the Word is the only medium of conjunction
of heaven with the church;
therefore when the Word is cast out of the heart
that conjunction is dissolved;
and because man is then left to hell
he no longer acknowledges any truth of the church. 

There are two things
by which heaven is closed to the men of the church.
One is the denial of the Lord's Divine,
and the other is the denial of the holiness of the Word;
and for this reason
that the Lord's Divine is the all of heaven,
and the Divine truth,
which is the Word in the spiritual sense,
is what makes heaven;
which makes clear
that he who denies the one or the other
denies that which is the all of heaven,
and from which heaven is and exists,
and thus deprives himself of communication
and thence of conjunction with heaven.
To profane the Word
is the same as "blaspheming the Holy Spirit,"
which is not forgiven to anyone,
consequently it is said in this commandment
that he who profanes the name of God
shall not be left unpunished.
