"I know you love your wife Joe. Do you know how love is defined? Josef Pieper described it in this way: Love is a fundamental YES to the existence of the beloved. Well, you know what contraception is? First of all it is a NO to your wife's fertility which is not something she has, but something she is [therefore contraception is a fundamental NO to your wife because of the intimate union between her body and her soul]. Secondly, contraception is a fundamental NO to the potential existence of the child. Therefore, this fundamental NO, inserted in the most intimate expression of conjugal love, contradicts the very nature of love [the YES to the existence of the other] and as such will inexorably erode the love between any husband and wife who practice contraception."
