Rom 16:17, 2 Cor 11:4, Gal 1:6-7, 1 Tim 6:3-5
The church should not teach anything other than the gospel that Jesus is the Christ. Many people try to teach the saints other than this gospel. (1 Tim 1:3-7, Rom 16:17)
1 Tim 1:3 As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine, 4 Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do. 5 Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned: 6 From which some having swerved have turned aside unto vain jangling; 7 Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.
Rom 16:17 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
Saints are easily deceived by other gospels. (2 Cor 11:4, Gal 1:6-7)
2 Cor 11:4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
Gal 1:6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: 7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
If we do not interpret the Bible as Jesus is the Christ, we lose the truth and quarrels arise within the church. (1 Tim 6:3-5)
1 Tim 6:3 If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness; 4 He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings, 5 Perverse disputings of men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself.
