BROTHERLY LOVE Concept that appears throughout the Bible, but the specific word for this type of love appears only in the NT. The word which is usually rendered “brotherly love” in the NT is the Greek philadelphia and is used only five times (Rom. 12:10; 1 Thess. 4:9; Heb. 13:1; 1 Pet. 1:22; 2 Pet. 1:7). A similar word, philadelphos, appears in 1 Pet. 3:8, and means “loving one’s brother.” However, the idea of brotherly love is much more extensive than these few occurrences.
