AC 7831 - remains & the Pascal lamb; AC 7840 - people of the church

AC 7831
. . . by "ten" are signified remains,
that is, truths and goods 
stored up by the Lord
in the interiors of a person;
and as remains are in the interiors,
and by them a person is prepared and initiated
to receive good and truth from the Lord,
therefore by "the tenth day" is here signified
a state of initiation of the interiors.
(. . . a person is regenerated by means of remains,
consequently is by them initiated
into receiving the influx of good and truth from the Lord;
and that by means of them
a person communicates with heaven;
for these goods and truths are from the Lord,
and not from man.)
. . . By the paschal animal is signified the good of innocence,
which is the inmost;
thus it is signified that this inmost,
together with the interiors in which it is,
should meanwhile be secluded
and withheld from such things as defile.
This state is a state of initiation of the interiors,
that is, of preparation
to receive the influx of good and truth from the Lord.
This is the holy thing which is contained in these words . . ..

AC 7840
People of the internal church
are they who do what is good to the neighbor
from the affection of charity;
but people of the external church
are they who do it from obedience.
Every person while being regenerated
first becomes a person of the external church,
and afterward a person of the internal church.
