Beyond the profane language, human love is strongly marked by the divine. The Song of Songs 8:5-7 sheds light on the debates on uniqueness, the indissolubility of marriage, feminism, the problem of "gender", the legislation of marriage, the freedom of choice of the spouse and finally the human person in his aspiration to transcendence and integral fulfillment. The exegetical problematic concerns the meaning of words, their symbolism, their grammatical and syntactic context, the figures of grammar and rhetoric that structure all poetic language, the shadowy points of writing such as that of ???????? or the suffix pronouns. The fundamental methodology is that of intertextuality, supported by textual criticism, semiology, symbolism and rhetoric. The love is defined as a quadruple dynamic of rationality with the Absolute, the cosmic corporality, the otherness and the social reciprocity and the assumed and responsible ipsity. Love is a flame of God, a power of reciprocal fullness.
