Mutual love and charity bring such people together into
one despite the variety among them, because it draws
unity out of variety. When everyone practices charity, or
loves each other, then no matter how many people there
are—even if they number in the hundreds of millions—
they share a single goal: the common good, the Lord’s
kingdom, and the Lord himself. Variety in doctrine and
worship are, again, like the variety of senses and organs
in the human body, which contribute to the perfection
of the whole. When doctrine or worship varies, then the
Lord, working by means of charity, affects and acts on
each of us in a way uniquely suited to our personality. In
this way he fits each and every one of us into the order of
things, on earth just as in heaven. Then, as the Lord himself
teaches, his will is done on earth as it is in heaven.
