From the article:
“Reception of the Eucharist—communion—and marital relations are both meant to be life-giving acts, fruitful acts. Both involve great risks, and, as such, require great faith in the spouse. In both, there is to be a communion of flesh.”
Comparing the marital union between husband and wife to the union of Christ with his bride, the Church, has long been a theme in Catholic theology. [It was also a theme in the religious Puritans of New England, who viewed marital love as a prefigurement of the union with Christ to be experienced in heaven.] So I can well accept the writer’s use of this theme.
It is Catholic teaching, of course, that contraception is a grave matter, and that if engaged in with full knowledge and consent, cuts one off from sanctifying grace.
But teaching about this has been so lacking for so long, I wonder to what extent full knowledge and consent are present. The teaching needs to be reintroduced and emphasized.
Still, the act itself remains disordered, and as such, has many adverse effects on families and societies.
