No Other Gospel Needed  

Galatians 1:1-9 (NASB)
¹  Paul, an apostle (not sent from men nor through the agency of man, but through Jesus Christ and God the Father, who raised Him from the dead),
²  and all the brethren who are with me, To the churches of Galatia:
³  Grace to you and peace from God our Father and the Lord Jesus Christ,
⁴  who gave Himself for our sins so that He might rescue us from this present evil age, according to the will of our God and Father,
⁵  to whom be the glory forevermore. Amen.
⁶  I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel;
⁷  which is really not another; only there are some who are disturbing you and want to distort the gospel of Christ.
⁸  But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed!
⁹  As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed!

2.     The Authority Of The True Gospel Messenger

Galatians 1:1-2 (NASB)

²  and all the brethren who are with me, To the churches of Galatia:

Galatians 2:4-5 (NASB)
⁴  But it was because of the false brethren secretly brought in, who had sneaked in to spy out our liberty which we have in Christ Jesus, in order to bring us into bondage.
⁵  But we did not yield in subjection to them for even an hour, so that the truth of the gospel would remain with you.
