Firstly, I tried some keyword searches on the forums to find an comprehensive argument against contraception, but I was specifically looking for something mostly from Scripture, as I intend to present an argument against contraception to Protestants. I didn’t find anything very quickly regarding these specific counterpoints, so I started this thread.
I myself and basically convinced of the Catholic position that contraception is wrong. And I was looking for some Protestant sources in agreement with this. However, I came across this article, and I was curious for a Catholic rebuttal of the counterpoints here.
*]Onan was not killed for spilling his semen, but for adultery
*]Other mentions of spilled seed or failure to fertilize are not condemned because of that reason
If this belongs in another board, I apologize, this seemed like the best one.
