BROTHERLY LOVE — philos, 'loving', + adelphos, 'brother': affection between kin, and in the New Testament the love of fellow believers as family. ⚠ The early church took a word that meant literal sibling-love and stretched it to the whole community of faith: 'love one another with philadelphia' (Romans 12:10), 'let philadelphia continue' (Hebrews 13:1), and at 1 Peter 1:22 a philadelphia that must be anypokritos, 'unfeigned', and ektenēs, 'stretched to the full'. It is narrower than agapē — love specifically of the brother and sister — and Peter treats it as the immediate proof that the new birth has taken. The American city was named for it. → first discussed at 1 Peter 1:22
