A theology which does not want to speak out of the mouth of the Lord and have as its direct aim eternal salvation has no place in the Christian Church and has forfeited its right to be heard. It is an exotic plant, not one which the heavenly Father has planted (Matt. 15:13). In the Church only God’s Word (λόγια θεοῦ) should be heard, and that for the purpose of saving men (John 20:31,1 Pet. 4:11; 1 Tim. 1:4; 6:3).
