I appreciate the responses. I can’t help but wonder if there are any former Protestants that could give me an answer that is easier to understand.
So far the only responses have been Catholic dogma and Catholic books.
Could anyone perhaps furnish a common sense argument for why someone shouldn’t perform sodomy during a pregnancy?
What are the primary purposes of sex?
(1) The most obvious one is reproduction. While there may be more to it in humans, it can’t be denied that it’s the mode of reproduction for all sexual species. (There may be a few animals that reproduce both sexually and asexually, but even in those cases, sex is directed at reproduction.
(2) In social species like humans, sex also is directed at leading to greater unity between the couple. A healthy sex life is one factor that keeps the relationship strong and healthy, and a major reaaon for that is to keep the parents together for the rearing of children, though it also serves our emotional needs.
(3) Perhaps less apparent, but the Church also understands sex and marriage in a theological way. The couple represents the two persons of the Trinitarian Godhead, with the love between them open to a third person. It’s the image of the family. The bliss of sex is also, believe it or not, at the moment of perfect union between the two couples, is also seen as an image of the bliss of God.
The scientific method can’t prove purposes, though it can give data from which a rational mind can make conclusions as to what a thing’s purpose is. Someone who os ostensibly a Christian shouldn’t reject the idea that we have purposes in our live, ends towards which we are directed. Our highest end is to find God, but as an animal, maintaining health, reproducing, etc… are also important ends (though they don’t trump God and the pursuit of Goodness and Truth).
We err into sin when we intentionally frustrate the ends of our species. This isn’t simple abstinence, but of wanting to “have your cake and eat it to.” In regards to sex, as a species and as a function, wanting to have sex but intentionally altering the function so as to prevent its ends is morally wrong. This doesn’t mean every sex act must be reproductive, but that it must be performed in a way consistent with the ends towards which it’s ordered.
And if you don’t like that, God struck down Onan for spilling his seed. Night emissions were seen to cause uncleanliness among the Jews, and the Christian community has consistently believed such things to be intrinsically disordered and against God’s laws since the first century, and there only arose serious controversy over the point about 80 years ago.
