Actually, you're incorrect as in applies to Catholic teaching. Maybe your belief system says so.
There is nothing wrong with spacing births for legitimate reasons, such as the surgery I am having next month. It all has to do with intent. And whether you love in a nonlife giving manner, which mocks the life giving love of the Father.
Off to retreat, I have a feeling you and I will continue this conversation later.
During retreat, make sure to confess the sin of avoiding children while enjoying conjugal relations...
Natural Family Planning (NFP)
NFP is an umbrella term for certain methods used to achieve and avoid pregnancies. These methods are based on observation of the naturally occurring signs and symptoms of the fertile and infertile phases of a woman's menstrual cycle. ....... No drugs, devices, or surgical procedures are used to AVOID PREGNANCY. (emphasis mine)
From http://www.nccbuscc.org/prolife/issues/nfp/index.shtml
Translation: We've found a way to circumvent God's will for catholic families to propogate children...yahoo ! Now, I ask you, does this violate the spirit of the teaching? Of course it does !
Also this is bullcr*p from bishops, the same crowd who supports illegal aliens, high taxes, etc, etc.
