All

I did a quick word study of the Greek word πᾶς, which is translated as "all." As in "all things," "everyone," and "everything." My interest was in New Testament moral exhortations directed toward "all." Many New Testament imperatives can be interpreted narrowly, as directed toward the church rather than toward the world, toward all, toward everyone. So I went looking for moral directives related to πᾶς.

For example, Philippians 4:5: “Let your gentleness be known to all.”

Some πᾶς imperatives are two-tiered. For example:

1 Thessalonians 5:15: “Always seek to do good to one another and to all.” 

Galatians 6:10: “Let us do good to all, especially to those of the household of faith.”

The in-group is noted—"to one another" (i.e., the church) and "the household of faith"—but set against the universal backdrop: "Seek to do good...to all" and "Let us do good to all." 

Other πᾶς exhortations:

Romans 12:18: “If possible…live peaceably with all.”

Romans 12:17: “Provide what is good in the sight of all.”

Titus 3:2: "Showing all gentleness toward all people.”

Focusing on πᾶς isn't the only place where we find a note of universality in Scripture. But this spotlight does bring to light moral expectations that a lot of Christians seem to ignore:

Do good to all.

Let your gentleness be known and visible to all.

Live peaceably with all.
