We looked at Humanae Vitae here last year. The section cited in the final document of the synod bishops looks at the responsibilities of marriage, not as much the rights. Sometimes the notion of duty makes us squeamish (and to be sure, married couples aren’t the only ones who might shy away from responsibility). Let’s read:
68. “Blessed Paul VI, in the wake of the Second Vatican Council, further developed the Church’s teaching on marriage and the family. In a particular way, with the Encyclical Humanae Vitae he brought out the intrinsic bond between conjugal love and the generation of life: ‘Married love requires of husband and wife the full awareness of their obligations in the matter of responsible parenthood, which today, rightly enough, is much insisted upon, but which at the same time must be rightly understood… The exercise of responsible parenthood requires that husband and wife, keeping a right order of priorities, recognize their own duties towards God, themselves, their families and human society’ (No. 10). In the Apostolic Exhortation Evangelii Nuntiandi, Paul VI highlighted the relationship between the family and the Church”.(Relatio Finalis 2015, 43)
There is indeed a bond, but “generation of life” limits us too much here. I would hope the church views this as not just a biological reality, but also a social and spiritual effort. Married couples also contribute in a special way to assist children generally in society to be reared and formed as human beings ready to receive the fullest revelation of their potential in God. More so than clergy or religious? I wonder.
