So far as testing God or trying God, offer these:
Matthew 4:7 Jesus said to him: It is written again: Thou shalt not tempt the Lord thy God.
Luke 4:7 Jesus said to him: It is written again: Thou shalt not tempt the Lord thy God.
Genesis 1:28 And God blessed them, saying: Increase and multiply, and fill the earth, and subdue it, and rule over the fishes of the sea, and the fowls of the air, and all living creatures that move upon the earth.
As for Onan’s sin, I wish the n-Cs’d make up their minds about this. Some tell me it’s masturbation, and others say other stuff like you’ve heard.
I believe that his sin was straight up disobedience, since he knew what God’s willl was and chose to rebel against it and in the process deprive his brother’s widow of anyone to support her or protect her. In effect casting her into prostitution, since to my knowlege there wasn’t a big job market for women in those days outside the home.
So far as the other info you’ve got here, it all looks pretty good. The sudden change in 1930 is a chilling indictment against the n-C churches, and in point of fact, there are historical documents showing that even the pagans abhored the use of contraceptives.
As for NFP being the same thing: not so since the NT teaches Christian
abstinence by agreement for a time for spiritual reasons (1st Corinthians 7:5 Defraud not one another, except, perhaps, by consent, for a time, that you may give yourselves to prayer; and return together again, lest Satan tempt you for your incontinency.) and I’d point out that not wanting to use drugs to prevent conception (ask 'em what the Greek word in the NT is for “witchcraft”…It’s where we get the word “Pharmacy” from!) in obedience to God is certainly better than going into witchcraft and rebellion against God.
The abortifacient nature of contraceptives is certainly another point, since they will cause a new fetus to detach from the womb wall and die I understand.
Song of Solomon is all about love, not sex, though the language is certainly passionate enough. This is nothing more than them using a passage of the Bible to rationalize what they wanna do anyway. You can easily embarrass them by pointing out that in all that heat…it nowhere says that she broke to go take her pill or that he put on a condom. Using Song of Solomon like that is pretty lamely grasping at straws IMO. A married couple’s sex for pleasure is fine so long as the act is open the the possiblity of new life from that union, since pleasuring each other is a legitimately loving part of the act. (Stop and think about it…does
anyone have sex
not for pleasure?!)
In the end it’s all gonna be a lot of their rationalizations to justify themselves. If they refuse to listen, you know what the Lord said to do when someone rejects your good news message. Dust your feet off against them…and walk off, leaving them in the Lord’s hands.
Pax vobiscum,
