It is vital to recognize the dangers of intimacy with the world, especially with those who show gross disrespect for godly standards. (Compare 1 Corinthians 15:33.) Yet, when the Bible counsels to “work what is good toward all,” the word “all” includes those who do not share Christian beliefs. (Galatians 6:10) Evidently, under some circumstances first-century Christians shared meals with unbelievers. (1 Corinthians 10:27) Hence, today Christians treat unbelievers in a balanced way, viewing them as their fellowmen.—Matthew 22:39.
It would be wrong to assume that a person is indecent or immoral simply because he is not acquainted with Bible truths. Circumstances and people vary. Hence, each Christian must decide to what degree he will regulate his contact with unbelievers. However, it would be unnecessary and unscriptural for a Christian to isolate himself physically as anchorites did or to feel superior as the Pharisees did.
