Outline
- of one mind, of one accord
- This word is made up of two words syn (together with) and psychos (soul, self, inner life, or the seat of the feelings, desires, affections). So the word refers to being 'united in spirit' or harmonious (BDAG). Paul desired the Philippians to be united in their affections—one in Christ in all desires! Phl 2:2 is the only occurrence of this word in the NT. (Wayne Steury)
