"I should say that my wife and I, while still Protestants, found the first edition of this work to be so luminous and compelling as to help change our minds on the matter of contraception."

"A veritable mine of information, Sex and the Marriage Covenant is must reading for anyone concerned with marriage, sexuality, and the family."

"Your ministry is truly a blessing of the Spirit not only for the Church, but for every human being. I think the book, Sex and the Marriage Covenant, should be read by every high school kid. I think you should be required to read it before getting married!"
