Feeling lonely is something everyone feels at one time or another, nuns included. But do nuns feel it more acutely because they make a vow to be celibate, that is, nuns choose to not have 1) sex or 2) romantic or exclusive relationships?
In a recent comment, Marilyn asked what I think of the vow of poverty. She pointed out the different meanings of the word poverty: 1) lacking resources and 2) renouncing the right to individual ownership. The vow of poverty has more to do with the second meaning.
