“Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.” (1 Corinthians 1:10)
The days of the early church were the days of its greatest power because they were days of its greatest unity. “They, continuing daily with one accord . . . and singleness of heart.” “And the multitude of them that believed were of one heart and of one soul: . . . and great grace was upon them all” (Acts 2:46; 4:32-33). It was not long, however, before divisions, contentions, and schisms crept in. Therefore, the New Testament contains many exhortations toward a restoration of the unity—and thus the power—of the early church. Note the following examples.
“Be of the same mind one toward another” (Romans 12:16). “Now the God of patience and consolation grant you to be likeminded one toward another according to Christ Jesus: That ye may with one mind and one mouth glorify God” (Romans 15:5-6). “Be perfect, be of good comfort, be of one mind, live in peace; and the God of love and peace shall be with you” (2 Corinthians 13:11). “Stand fast in one spirit, with one mind striving together for the faith of the gospel” (Philippians 1:27). “Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind” (Philippians 2:2). “Finally, be ye all of one mind, having compassion one of another, love as brethren, be pitiful, be courteous” (1 Peter 3:8).
Real unity, of course, must be both “the unity of the Spirit” and “the unity of the faith” (Ephesians 4:3, 13), and “the same mind” must be nothing less than the mind of Christ. “Let this mind be in you, which was also in Christ Jesus” (Philippians 2:5). HMM
