What do we mean when we say we love someone? Are there differences between the love that exists between parent and child; between lovers, friends, or siblings; and between teacher and student? Are there different forms of love that might apply to one relationship and not to another?
For example, what is “tough love” that the Christians love to use (pun intended)? Can love be a justification to hurt another? For thousands of years humankind has persecuted, tortured, killed, maimed, and abused itself in the name of God, who is love.
