I told you last week that HV used circular reasoning: What we are telling you comes from natural law, and we know what natural law is because we are the ones to say what it is. Their only source for their natural law argument is themselves.

Now I am giving you a completely accurate description of the way the celibates who developed Catholic sexual morality reached their conclusions. They felt that sex had to be "justifed" by saying it was for procreation, because -- and I can quote all sorts of Church fathers on the topic -- sex was nasty and taking pleasure in sex was wrong.

To sum up: They start with a bad premise, and use bad reasoning in their argument.  No one should take such statements seriously.
