When it comes to sex education programs, the Catholic Church is called  old-fashioned and callous about teen pregnancy and disease. But governments that mandate sex education in the schools are fooling themselves about its effectiveness, the Vatican newspaper says.

The newspaper looked specifically at New York City, where students in middle school and high school will be required to attend a semester-long course in sex education.

To avoid religious controversy, chastity will be cited among birth control methods and teachers will have to speak about sex with some caution in the New York courses.

Still, Archbishop Timothy Dolan of New York criticized the mandatory program as usurping the rights of parents to educate their children in line with their beliefs and values.
