[Verginius Rufus]

The Latin word caelebs means "unmarried" (referring to a man). It doesn't necessarily imply anything about abstaining from sexual activity. An ancient Roman senator who was caelebs probably had slave women to sleep with (or slave boys, if he was so inclined).

[O6ret]

Regardless of the word origin the Catholic Church has ALWAYS taught that celibacy meant abstinence from sexual activity. Period.
