Vernacular and a surprising etymology

"Latin is rigid, a dead language, no-one understands it, it is inaccessible, exclusionary....

But something said in the vernacular is alive, it's inclusive, accessible to all...."

I decided to investigate the etymology of vernacular.?The results surprised me. 

The online OED offers the following:

vernacular, adj. and n.

2. a. Of a language or dialect: That is naturally spoken by the people of a particular country or district; native, indigenous.

6. Of arts, or features of these: Native or peculiar to a particular country or locality. spec. in vernacular architecture, architecture concerned with ordinary domestic and functional buildings rather than the essentially monumental.

Forms:  Also 1600s vernaculer.

Etymology: < Latin vernāculus domestic, native, indigenous (hence Italian vernacolo, Portuguese vernaculo), < verna a home-born slave, a native.

The Latin adjective occurs in a large variety of applications; the restricted use common in English is represented by vernacula vocabula in Varro.

Lewis & Short offer the following: (highlighting added)

verna, ae, comm. [root vas, to dwell; Sanscr. vāstu, house; Gr. ἄστυ, city], a slave born in his master's house, a homeborn slave.
