So a RCC married couple could live their entire married lives using the natural method of birth control with great success and NEVER have a child. This would be completely within the teaching of the catechism and yet defy the very spirit of the law (IMHO). The couple would be continuing to have sex within the confines of marriage while avoiding the God-decreed command to be fruitful and multiply.
I don’t see any Biblical support for this RCC teaching. Where in the Bible has this been practiced by God’s people and encouraged by God?
Granted, there are cases where christian women can have their “wombs closed by God” but infertility is quite a different thing from purposefully avoiding children in marriage through natural means (or any means). When the church condones this behavior, and even encourages such, I must question their theological acuity.
