Exactly. I am Catholic, so I don’t memorize verses (not that there is anything wrong with that), but I believe it was actually a preferred state for those who had the strength to do it.
No, but you pray the Rosary which requires a lot of memorization; even the responses during Mass, which are scripturally-centered.
I, too, am single (and celibate) and NOT gay; but people tend to pigeon-hole single women as lesbians. Oh! Well!
