In Jewish life, for thousands of years already, is sex not something dirty or even naughty. Rather, it is part of G^d’s generosity. Like He wants us to enjoy a lot of things—within limits—sex is there to enjoy too.
Sex is for a man even an obligation to his wife, the way she likes it. And the Sages point out that it’s good for one’s mental and physical health. And, of course, it’s a way to have children from both partners.
And the Torah itself even points out that sex may make the parties bond and recommends it. So much good!
In fact, sexuality is so holy that it should not be cheapened. The holiest people (the High Priest, the Nazir) should not refrain from it. One should be very careful with sex—not because it’s filthy but because it’s sacred.
The walls in the Holy of Holiest depicted couples ‘in intimate embrace’ symbolizing the closeness and bond between the Divine and the Jews.
Compare that to classical Christianity. That has a problem with all earthly pleasures. In that worldview, sex is inherently sinful. A really pious person (monk, nun, cardinal, pope) should completely forgo it. And the regular faithful could use it, but mainly to have (many) children.
I’m deeply saddened about Christian commentary that crept into our Holy Tradition. The First Couple gets close to the border of Egypt, and suddenly, the First Husband sees, for the first time, how beautiful his wife is.
All these rabbis who praise their modesty. “She never showed herself, he never looked.” How can any learned Jew think that?! This is 100% assimilation to the classical, outdated, Christian worldview.
Of course, they saw each other’s beauty. Of course. And Rebecca fell from her camel when she first saw the First Son. And he didn’t. He was blind!
So, what could be the simple reason that he says that now, unexpectedly, he sees her beauty? It means that now he realizes that she is what one calls beautiful. That she is stunning in the eyes of many—not just in his vision.
