Why would virginity throughout marriage be better, and more Godly than having sex? For thousands of years, the priests of God were married, and had children. God is the same today, tommorrow and yesterday. The tradition of perpetual virginity(of Mary) and unmarried priests(tradition of Catholicism) are not scripturally based, and are humanly unsound. I'm sure they lead to a higher percentage of troubled persons becoming nuns and priests, to hide from their latent homosexuality(both priests and nuns), and anti-social tendency(in the case of nuns).
I don't mean to be-little your faith, or that of others, but the questions arise. People call the Seventh Day Adventists, or the Mormons a cult, for far less deviations from the Bible. The SDA are called a cult, because they want to worship on the Sabbath, and the Mormons are called a cult, because they called their leader infallible, and a prophet of God, just like the Pope.
So I'm guessing your not going to read St. Jeromes letters either?
If your feeling courageous enough to go to the website, scroll down to the gent named "Augustine of Hippo [SAINT DOCTOR]
When you see that, scroll down just a bit further to one of his writigs entitled "On Holy Virginity," I think you will find it quite beautiful, and enlightening.
Several other saints wrote about Holy Virginity also.
