The name that is transliterated as «Erastus» in English means «beloved.» (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that is reminiscent of signs such as «treasurer» or «city administrator of the city» (in reference to Romans 16:23). (Source: Missão Kophós )
