In Greek they have four words for love.
Storge, S-T-O-R-G-E, means
affection, the sort of love there ought to
be between their relations.
Philia, P-H-I-L-I-A, means
friendship.
Eros, E-R-O-S, is of course
the love between the sexes.
And Agape, A-G-A-P-E, is
love in the Christian sense, God's love for
man and the Christian's love for the brethren.
