All of it is the justification of a divine being. It is the opposite of science, Aquinas BEGINS with the assumption of the divine being and then invents reasons to support it.
"Aquinas states that common sense tells us that the universe works in such a way, that one can conclude that is was designed by an intelligent designer."
*sigh* Even Aquinas admits he cant 'explain' it....
There are two methods to discern the will of "god".
Words written by men and observation of the created universe.
There are two species where females are sexually receptive at all times but only fertile part of that time; humans and bonobo chimps.
The fact that human females can have sex even when not fertile is pretty solid evidence that "god" had more than procreation in mind for sex. If not, women would have "seasons" like all the other mammals.
Further, take the bonobo. Innocent as all animals are. They have a matriarchal social order and spend a ridiculous amount of time engaged in sexual acts, including sodomy (oral).
So do we believe words on paper put there by men or what can clearly be observed in "gods" creation itself?
"God" made women to engage in sex without being fertile. What he made contradicts what you believe.
Unless you believe in "douchebag god" who built us temptable, in a world full of temptations, and damns us for eternity if we give in to the process "he" created in the first place.
