Is premarital sex a mortal sin?

The view on premarital sex as a mortal sin varies significantly across different religious and cultural contexts. In many branches of Christianity, particularly within the Catholic Church, premarital sex is considered a serious sin, as it goes against the teachings on chastity and sexual morality. However, other religious traditions and secular perspectives may not view it as sinful at all. Ultimately, whether it is considered a mortal sin depends on individual beliefs and the teachings of one's faith.
