Birth control
Catholicism – almost all types of birth control are a sin (except Natural Family Planning or abstinence). The Catholic Church had no official policy over Contraception until 1930 when Pope Paul VI officially banned Catholics from using birth control pills, most forms of contraceptions, and even condoms. The Church believes sex is for a husband and wife to make a baby, and sex must always be open to life (possibility of making a new human) and contraceptions would be sinful as it blocks pregnancy even though the Bible does not ban contraceptions.
