What does Jesus mean by "Love"?

We recognize our graduating seniors this Sunday at Holy Family, and we have a beautiful Gospel with which to do so. Jesus commands his disciples (and us): "As I have loved you, so you must also love one another." What does Jesus mean by "love" and is his meaning different from the way we usually understand it? Is he commanding us to have warm feelings for each other? To like each other? We explore the various meanings of "to love" in Greek and look at how Jesus uses the word "agape" to define what he means by love.
