The cross is a symbol of love because it resembles geometrically the form of a man with arms outstretched, about to embrace, ready to love. Psychoanalysis has demonstrated man's inability and fear to love. Crucifixion, therefore, represents a warning. It shows the man who terrified mankind by loving and demanding complete love, with outstretched arms, ready to embrace, but tied and nailed in such a way that he could no longer do so.
