Sexual intercourse (The marriage act) is intended by God to be ( God has a plan for love, marriage and sex) at least implicitly (You don’t have to be thinking this explicitly) a renewal of the marriage covenant (I love you and I take you once again for better and for worse until death do we part).
A review of Sex and the Marriage Covenant by a non-Catholic Christian:
” Chapters 6-8 were very interesting and I think very good.
Chapter 9 gave me a better understanding of what Infallible teaching is, because I had never heard of it before. I think that is helpful to have a deeper understanding of how Catholic teachings work.
Chapters 11 and 12 I would say are definitely important to those who are going to teach NFP.
Chapter 17 was very good and very relevant. I actually had that discussion here at work about whether Onan was sinning by spilling his seed or by his evil intentions. So chapter 17 provided a solid explanation of the biblical context of the account of Onan. I am glad I read it.”
Sex and the Marriage Covenant is now available as an e-book.
