celibacy is not a higher path

Celibacy is not a higher path, even though that is often the line people pick up from the Church. You might ask: if it isn’t a higher path, a holier way, why would anyone in their right mind choose it? But it isn’t a ‘higher path’. Why did the Church teach in the past that sex was always sinful? It did in the past. Even within marriage. And why did women who gave birth have to be ‘churched’ before they could go back to Mass? And did I miss it but has the Church ever apologised for the negativity it taught about sex?
