Abstaining from sex to purposefully avoid fertilization is a form of contraception, particularly when the abstinence happens to match the female's normal cycle.
Let's read your own posted defintion:
Intentional prevention of conception or impregnation through the use of various devices, agents, drugs, sexual practices, or surgical procedures.
Yes, thank you for admitting the Roman Catholic church has approved a practice that avoids conception.
Hey, stop trying to argue that your own denomination hasn't caved, when it has.
No, I will continue to state the truth regardless of how many times you lack accuracy in your statements.
That being the case, it is understandable that you would try to argue that, oh well, the Catholic Church has caved also.
But the argument that you have presented shows that it has!
Either that, or join the real Church.
Already have, thank you. Perhaps you'll pay us a visit someday?
