The Greek comparative adjective alypoteros (ἀλυπότερος) means less sorrowful or freer from grief — composed of the alpha-privative and lype (grief, sorrow). Paul uses it in Philippians 2:28, expressing his desire to send Epaphroditus back so that the Philippians may be less anxious, and he himself less sorrowful.
This tender word reveals the apostolic heart of Paul. Even in his imprisonment he is deeply concerned for the emotional and spiritual welfare of his friends. Epaphroditus had been ill to the point of death, and the Philippians were grieved. Christian community is marked by this sharing of one another's griefs and joys (Romans 12:15). The goal of gospel fellowship is that we should all be less sorrowful — bearing one another's burdens (Galatians 6:2).
