Nowhere does the Bible command Christians to procreate. God told the first human couple and Noah’s family: “Be fruitful and become many and fill the earth.”
But this command was not repeated to Christians. ( Genesis 1:28 ; 9:1 )
Hence, married couples may decide for themselves whether they will raise a family, how many children they will have, and when they will have them.
The Scriptures, likewise, do not condemn birth control.
From a Biblical point of view, then, whether a husband and wife choose to use some nonabortive method of contraception is really a personal decision.
Why, though, does the Catholic Church condemn contraception?
There we have it, commands in the Old Testament are meaningless if they are not repeated in the New Testament.
Ps. I use contraceptives.
