“[I]n truth, all men know that they who are under the power of this disease [the sin of covetousness] are wearied even of their father’s old age [wishing him to die so they can inherit]; and that which is sweet, and universally desirable, the having of children, they esteem grievous and unwelcome. Many at least with this view have even paid money to be childless, and have mutilated nature, not only killing the newborn, but even acting to prevent their beginning to live” (Homilies on Matthew 28:5 [A.D. 391]). – John Chrysostom
The so-called “birth control” pill – shown above – is indeed an abortifacient. It actually performs an embryonic abortion. This has been proven by medical doctors across the world. Randy Alcorn has a short article on it here.
There is what some in the west call Natural Family Planing, which is perfectly ethical and godly. It has to do with identifying the signs of a woman’s fertility. Here is information on that.
Regarding how Chrysostom ties receiving inheritances to abortion, I would say that the same thing is happening in our day but from a different angle. Many couples now would rather NOT have children so that they can enjoy the inheritance of their culture – hobbies and luxury. There are legitimate reasons for not having children but I think that the “we cannot afford them” clause is grossly abused today. What I think many people mean to say when they refer to not affording children is that they cannot afford the lifestyle of their choice if they have children.
