"I believe that few faithful Catholics [who] prayerfully read Humanae Vitae and seek out further instruction should doubts arise would not find the teaching true to God's plan for sexuality."
Most Catholics today fail to follow Humanae Vitae, Smith acknowledged. But rather than finding this figure discouraging, she sees hope in a study finding that Church teaching on sexuality is accepted by 37 percent of Catholic women between the ages of 18 and 34 who attend Mass weekly and go to Confession at least once a year.
"In a Church where the teaching is rarely presented and a culture that mocks the Church's teaching, such compliance is astonishing," she said.
And there are other encouraging signs that the Church is working to better reach people with the message of Humanae Vitae, Smith said, such as recent efforts by the U.S. bishops to teach about the issue and encourage priests to do so as well.
In addition, she said, diocesan family life offices and young seminarians and priests have the training and desire to teach and promote Natural Family Planning, through which a couple uses a woman's natural fertile and infertile periods to pursue responsible parenthood. Unlike contraception, this method is accepted by the Church because it cooperates with human fertility rather than trying to stifle it.
Smith also noted marriage preparation programs that address cohabitation and contraception, as well as new teaching materials inspired by Theology of the Body, websites with resources and testimonies that are widely accessible, and an increase in faithful Catholic colleges and universities.
"My count indicates there are about 40 conferences being held that feature support of Humanae Vitae in the U.S., not to mention the webinars and likely hundreds of supportive pieces being published in print and online journals and blogs," she added.
"More of all of this needs to be done, but a tremendous start has been made."
