A form is more perfect as its constituents are distinguishably
different but still united in some particular way. In
support of this, angels have cited the communities in the
heavens. Taken all together, these communities make up
the form of heaven. They have also cited the angels in
each community, saying that the more clearly individual
angels are on their own—are therefore free—and love the
other members of their community on the basis of their
own affection, in apparent freedom, the more perfect is
the form of the community.
—Divine Providence 4:4
