What’s the Difference Between Contraception and NFP?
Natural Family Planning is the knowledge of a couple’s fertility. It is a knowledge base about a couple’s ability to conceive a child.
The application of this knowledge in a particular marriage is called responsible parenthood. The couple either decides to try to achieve a pregnancy or to avoid by timing their use of the privileges of marriage according to the knowledge of their mutual fertility. (The man, if healthy, is fertile all the time. The woman, if healthy, is fertile about three or four days a month.)
Responsible parenthood differs from contraception in two ways: 1. There is no alteration of the bodies of either the husband or wife and this is a huge difference. 2. When the couple uses the privileges of marriage, they are not holding back at all or refusing to give everything they are, physically and spiritually. If they are infertile at the time, this is the result of the way God created them. They are giving themselves totally to one another AS THEY ARE AT THAT MOMENT. No one could require more. Further, God never asked couples to use the privileges of marriage at any particular time. That decision is completely theirs. So, in the marital act during an infertile period, husband and wife who are applying the knowledge of their fertility (NFP) responsibly (responsible parenthood) are giving everything they are at that moment to one another.
The intention is also different. The NFP couple realizes that in every marital union there is a chance (perhaps remote) of conceiving a child and they accept this possibility. The contracepting couple (even if only with condoms) has a positive intention against confepction.
An example might help: I want some money from a bank. It makes a huge difference whether I go to the bank and draw the money out from a checking account or whether I approach a teller with a gun and “withdraw” $100. Either way, I get the $100, but one act is radically differnt from the other.
