His Holiness on Marriage as Witness:
I think we priests can learn from married couples, from their suffering and sacrifice. Often we think that only celibacy is sacrifice. But in getting to learn the sacrifices of married persons - think of raising children, the problems that arise from that, the fears, the suffering, the ailments, rebelliousness, or just think of the first years of having children, with sleepless nights attending to crying babies - there is much we can learn from their sacrifices, and our own sacrifices.
Together with them we can learn how beautiful it is to mature in suffering and to work for the sake of others. Don Pennazza, you have cited the Vatican Council which affirmed that Matrimony is a sacrament to save others - above all, this means, to save the other, the spouse, husband or wife, but also the children and ultimately, the community. Even we priests are able to mature in our encounters with our married parishioners.
