TCR 700-701 - the holy treasure that is Holy Supper

TCR 700-701
But because real Christianity is now for the first time arising,
the new church meant by the New Jerusalem in Revelation
is now being established by the Lord;
in this God the Father, the Son and the Holy Spirit are acknowledged as one,
because they are in one person.
It has therefore pleased the Lord to reveal the spiritual sense of the Word,
so that this church may reap
the real benefit of the sacraments of baptism and the Holy Supper.
This comes about when people see with the eyes of their spirit,
that is, with the understanding,
the holiness hidden within them,
and grasp this holiness for themselves
by the means which the Lord taught us to use in His Word.

Without the disclosure of the spiritual sense of the Word,
or what is the same thing,
without the revelation of how natural things correspond to spiritual ones,
the holiness of the sacrament which is the subject of the chapter
could not more be inwardly acknowledged than a treasure hidden in a field.
