In Christian theology, the sexual act is an icon of the Trinity and of the saving relationship between Jesus and the Church.
It is an icon of the Trinity because God is a communion of persons, who all completely give of their entire selves to each other. The person of the Father subsumes his entire existential being and substance to beget the Son, who, composed of the same divine essence, gives back the same total self-giving love in turn to sustain the Father. This total self giving of two divine persons begets the holy Spirit, who is interpreted to be the love between the Father and Son that is shared between them.
