Leviticus 12:1-6
I guess the bible does bend the rules in the Catholic’s favor.
Chapter and verse?
It's no different than church sanctioned divorce relabeled and repackaged as "annulment".
Preventing conception for the purpose of sex without procreative ability is the same no matter what method is used. NFP is no different than what Onan did.
I don’t condemn the rhythm method. It is not for me to do that, but really don’t see it preached in the Bible either. The 1 Corinthians 7 reference is not about contraception. The implication is a couple would abstain for faith reasons, maybe taking a vow, or part of fasting and prayer; or if one or both are ill. The entire theme is get married so you won’t burn in lust and give Satan an opportunity to defile your sanctification. So I don’t see the scriptural support there and one would need to wrest the words to come up with the rhythm system.
As Gamecock mentioned, and I emphasize, in many evangelical churches any chemical birth control is seriously frowned upon in some outright taught not to do. One reason is the same as the Catholic church and another some see the use as harmful to the mother’s health.
Then again as a proud product of the Catholic rhythm system, even I know that no means man uses can stop the will of God.
Finally, there is a logical flaw in employing the rhythm system. If the purpose of the Catholic church’s contraceptive policy is to teach the faithful not to hinder the natural reproductive process of be fruitful and multiply (that is Biblical) and the purpose of intercourse is to only produce babies, then the rhythm system becomes a slight of hand to circumvent the church’s own policy.
That above is opinion and not judging others. I have plenty of beams in my eye, as any honest pilgrim to this earth has, to start pulling out specks in others. The Roman Catholic church has rules on this matter, and the best advice I have is for her faithful to clean house before casting stones at others and arrogantly telling others that you are praying for them when you should be wearing out your rosary beads bringing the Nancy Pelosi’s of your church back in line with your teachings.
