Christ accepted the Hebrew scriptures condemnation of contraception, as in the book of Tobit:
Tobias 6:17, 6:22
[Tobias becomes afraid because he has heard that Sara has been married seven times; every time on her wedding night each husband was killed by a devil. The Archangel Raphael then says to him:]
“Hear me and I will show you who they are, over whom the devil can prevail. For they who in such manner receive matrimony, as to shut out God from themselves, and from their mind, and to give themselves to their lust, as the horse and mule, which have not understanding, over them the devil hath power.” He then instructs Tobias to “…take the virgin [his wife] with the fear of the Lord, **moved rather for love of children **than for lust: that in the seed of Abraham thou mayest obtain a blessing in children.”
So this passage shows that sinful lust within marriage equals having no love for children within marriage. That would clearly condemn contraception.
