Im surprised this topic didn't draw much interest so i'll give my opinion and hopefully it provides some food for thought...
So, is it a sin to use contraception. I think it is. I refer to this bible passage...
"Judah got a wife for Er, his firstborn, and her name was Tamar.
But Er, Judah’s firstborn, was wicked in the Lord’s sight; so the Lord put him to death.
Then Judah said to Onan, “Sleep with your brother’s wife and fulfill your duty to her as a brother-in-law to raise up offspring for your brother.”
But Onan knew that the child would not be his; so whenever he slept with his brother’s wife, he spilled his semen on the ground to keep from providing offspring for his brother. What he did was wicked in the Lord’s sight; so the Lord put him to death also" Genesis 38:6-10
What was Onan's sin? What exactly was wicked in the Lord's sight that cause Him to take Onan's life?
In the Leviticus laws, when a man dies and leaves a widow his brother is obliged to take her under his wing and raise offspring
So, some people argue that the Lord killed Onan for not fulfilling his duty as commanded by the law of Leviticus
But there is a problem with that. The breaking of Leviticus laws are not punishable by death
I think the Lord killed Onan because he intentionally spilled his seed. U mite be wondering if this counts as contraception
Definition the deliberate use of artificial methods or other techniques to prevent pregnancy as a consequence of sexual intercourse
I think its a sin, If you look at it from a natural point of view, there is nothing natural about contraception.
If u want to make love to your partners without the little cuddly surprise after 9 months then its a good idea to track her/your menstrual cycle so u know when shes/you're most fertile and least fertile...
