Non in the Bible

So, do not allow anyone to judge [i.e., condemn] you for what you eat, or what you drink, or regarding [your non-observance of] a [yearly] festival, or a [monthly] "new moon" observance, or a [weekly] Sabbath day.

[In this state] there cannot be [such distinctions as] Greek [i.e., Gentile] and Jew; circumcised people and non-circumcised people; barbarian and Scythian [Note: These last two words refer to foreigners whose language was unintelligible and who were uncivilized heathens], or slave and free person; but Christ is all [that is important] and [He is] in all [of His people].

Conduct yourself with wisdom in your interactions with outsiders (non-believers), make the most of each opportunity [treating it as something precious].
