71. It is worthy of mention that the greater the number in any society in heaven and the more these make a one, the more perfect is its human form, for variety arranged in a heavenly form is what constitutes perfection, as has been shown above (n. 56), and number gives variety. Moreover, every society of heaven increases in number daily, and as it increases it becomes more perfect. Thus not only the society becomes more perfect, but also heaven in general, because it is made up of societies. As heaven gains in perfection by increase of numbers, it is evident how mistaken those are who believe that heaven may be closed by becoming full; for the opposite is true, that it will never be closed, but is perfected by greater and greater fullness. Therefore, the angels desire nothing so much as to have new angel guests come to them.
