Belloc said: Questions-if people should only have sex when woman is fertile to conceive a child, then why did God not make us like cats/dogs, to have sex only when we went into heat?
why make man and woman to have sex when she is not fertile...?? is it not cruel to give us feelings of intimacy outside the "heat" period....?
Belloc, although I agree with you on this, I don't think that your logic is acceptable. Your words can be summerized like this:
if we have intimate feelings it is because God wants it, and if God wants something then it is ok to fulfill it. it is like the islamic way of reasoning that "if he didn't desire to give, He wouldn't give the desire" or the popular saying that" all our desires are in us because He wants to fulfill them."
I have a big objection to this way of reasoning: Who gives "the intimate feelings" (as you call them) to some very young teenages and MR people? and to all those who must not marry? and to those whose spouses are made impotent in war?
CM may (rightly) say that it is because of original sin that people feel love for union when they must not. But someone who is anti-NFP can use the same logic to refute you by saying sth like this: It is because of orginal sin that you want *** when your wife is infertile.
