AC 3419 - What is charity? Who is our neighbor?

AC 3419 [3]
... charity is the affection of being of service to others without any end of recompense;
and also what is the neighbor toward whom there should be charity,
namely, all in the universe,
but still each with discrimination.

[6]
... in the supreme sense the Lord is the neighbor,
for He says:
Inasmuch as you did it unto one of the least of these My brothers,
you did it unto Me.
Matthew 25:40
