Your logic here is circular. On the one hand, you’re telling us to prove the Church’s teaching on sexuality. On the other hand, you’re rejecting the Church’s ability or authority to teach this, because of this teaching. With that kind of logic, we will never make it anywhere. Just thought I’d point that out. Furthermore, I have already told you that I know lots of families, with plenty of “experience” (as evidenced by the amount of children they’ve had) that have seen tons of fruit from these teachings. Celibacy is a higher calling. It offers an awesome gift from God back to Him as a sacrifice to become closer to Him. That is such an awesome concept! Not all people are called to it, but to say that someone who is called to it is less because of it, or it’s simply because he has less “sexual experience” is not only incredibly ignorant but also completely false in many accounts. Finally, you are wrong about VII. This is an urban legend and an accussation thrown out there to discredit the Church.
