Very highly in love. — The original here is difficult; but it seems best, with most good commentators, ancient and modern, to construe “in love” with “esteem,” and to make “very highly” (a very enthusiastic word in the Greek) an expletive attached to “in love,” implying “hold in a most extraordinary degree of love.” The bond which binds the Christian community to their directors is not to be one of “recognition” and obedience only (1 Thessalonians 5:12), but of holy affection above all.
For their work’s sake. — Our love is to be paid them not for any social or intellectual qualities they may have in themselves; it is the work which they have to do that should attract our sympathy. The original seems to mean that we are to love them, not only because they do such work, but also ‘for the sake of their work,” i.e., to help it forward.
Be at peace among yourselves. — Discipline to be observed towards equals, as well as superiors.
