"The person who knows only one language does not truly know the language"

BILLY found a good article  regarding the justification of maintaining the mother tongue of a person. There's  no doubt that we can competently learn about a culture or a religion without having to speak the language (Wiki-all-the-way!) but in order to comprehend fully, we need to be exposed to it as language is something that has been living chronologically with its society. However, this does not mean we should abandon the benefits in the ability to speak more than one language.
