'Non christians' in the Bible

He must also have a good reputation among outsiders [i.e., non-Christians], or else he could fall into reproach [i.e., from worldly people] and [therefore] into the devil's trap.

Therefore, I want the younger widows to get married, have children and manage their homes, so that they do not give the enemy [i.e., non-Christians] an opportunity for speaking against [the church].
