AC 4121 - relationships

AC 4121
. . . in themselves
goods and truths acknowledge
no other father than the Lord,
for they are from Him alone.
Consequently, all who are in goods and truths
are in brotherhood;
but still there are degrees of relationship
according to the quality of the goods and truths.
These degrees are signified in the Word by
"brothers," "sisters," "sons-in-law," "daughters-in-law,"
"grandsons," "granddaughters," and by other family names. 

[2] On earth
they are so named with reference to a common parentage,
however they may differ in regard to affections;
but this brotherhood or relationship
is dissipated in the other life,
and unless they have been in similar good on earth,
they there come into other brotherhoods.
At first indeed they for the most part come together,
but in a short time are separated;
for in that world it is not wealth that keeps people together,
but as just said, affections,
the quality of which is then clear as in a clear day,
and also the kind of affection
which one has had toward another.
