I knew supposed celibate nuns who were marriage counselors. I always thought that was a bit strange too. 😁
1 Timothy 3:1-7 The saying is trustworthy: If anyone aspires to the office of overseer, he desires a noble task. Therefore an overseer must be above reproach, the husband of one wife, sober-minded, self-controlled, respectable, hospitable, able to teach, not a drunkard, not violent but gentle, not quarrelsome, not a lover of money. He must manage his own household well, with all dignity keeping his children submissive, for if someone does not know how to manage his own household, how will he care for God's church? He must not be a recent convert, or he may become puffed up with conceit and fall into the condemnation of the devil. Moreover, he must be well thought of by outsiders, so that he may not fall into disgrace, into a snare of the devil.
Not.
It may interest you that Mother Teresa's religious order, the Missionaries of Charity (MC), has taught over 100,000 low-income couples in India to use NFP to space or delay pregnancies.
That's as of a couple of years ago. Probably much higher now.
From what I hear, Catholic, Hindu or whatever, couples are absolutely delighted to learn how their bodies work, and how to space or delay pregnancies (or prevent or even achieve pregnancies, as they choose) in a way that strengthens the marriage, has no drug/device side effects, is inoffensive to religious morals and and doesn't cost them a cent.
That's how a sane society would define "reproductive freedom."
