If there was ever a cliché then this is it. Yes, love is love but what is love? I saw on a comment thread recently a claim by one of the participants that God or Jesus had told him that there was complete moral equivalence between homosexuality and heterosexuality because we are all evolving into a state in which sex (or gender as people say nowadays) will not exist. I've heard this before, that homosexuals represent a kind of enlightened vanguard blazing a trail into the future. It's an old delusion.
The only place that sex, as in masculine and feminine or their initiating equivalents on the spiritual level, cannot exist is the unmanifest state, the one in which spirit and matter are not yet sundered and nothing is. The very act of creation involves a division which, whether you call it consciousness and form or spirit and matter or God and Nature, is the root of the sex difference. That goes right down to the very ground of reality in that for creation to take place, one must become two. If you don't want sex to exist then you don't want life to exist.
A rejoinder to this might be that we will all become androgynous but that is a category error in that it forces a pre-manifested condition into the world of manifestation which word I use here as an equivalent for creation even if they are somewhat different, metaphysically speaking. But if life is to be expressed there must be this duality of subject and object and that, right there, is the sex difference. It cannot be dispensed with if life is to be known and seen and touched and tasted and all the rest.
It may be that as humanity evolves each sex will become more refined in its form and expression, and people might confuse this as each one of them becoming more like the other, but the unique categories of masculine and feminine will remain. In Luke chapter 13 God is compared to a hen who gathers her brood under her wings but that does not make him any less God the Father. Great men can have great compassion but they are no less men. Great women can have high intelligence but they are no less women. One androgynous being can never complement and complete another androgynous being and it is this completing and complementing that makes the love between man and woman what it is. Apart from being a necessity for creation, the sexual division of beings is a great gift from God because it takes love to a new level.
Love is love but what people often mean when they say this is that love is sex. They smuggle in one thing by claiming it is another. My teachers told me that love was indeed love if it was pure and did not degenerate. Most of what is called love by propagandists is degenerated love that arises from and is intended to satisfy the ego not the soul.
