I listened to a Christoper West audio recordings where he explains the theology of the body of JP2 writings.
He keeps on saying how important it is to be open to new life within the marital act(sex). Using contraception is prohibited because it violates the very act of love.
I noticed though among Catholics who practice NFP (natural family planning) that they solely use it to prevent new life. I'm talking about people who have no problem to conceive a child. I never hear them saying we are trying to conceive a baby. I only see the announcements how they 'again' got pregnant unexpectedly. Probably because they made a mistake in calculations or couldn't abstain.
My question is: Doesn't this set NFP to the same level as contraception? Does the child always need to be expected?
I know there is nothing wrong to have an unexpected baby or to postpone having a baby. Don't the couples' always trying to avoid pregnancy changing the meaning of NFP use? Didn't it become to be 'open to new life but always try to prevent it'?
