Some of us remember when births weren’t controlled and pregnancies weren’t planned.
Contraception has been around MUCH longer than you have been alive, unless you’re a Highlander...in which case your population decrease is occuring at a much faster rate than the West’s.
It may have been around but ALL Christian Churches banned the used of artificial birth control. That was until the Lambeth Congress of 1930 when the Anglicans tossed that notion and began contracepting. Only the Catholic Church has maintained the ban on artificial birth control while approving natural family planning. Catholics who do not heed this teaching are in a state of sin.
