False Brethren in our ranks w/ another gospel????

[SDG]

In reading Galatians 1 and2 this week ... I am fascinated w/ Paul's response to the Judaizers of his day that sought to pervert the gospel by their works and traditions

Galatians 1:

No Other Gospel

6I am astonished that you are so quickly deserting the one who called you by the grace of Christ and are turning to a different gospel— 7which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ.

8But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned! 9As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let him be eternally condemned!

10Am I now trying to win the approval of men, or of God? Or am I trying to please men? If I were still trying to please men, I would not be a servant of Christ.
Paul Called by God

11I want you to know, brothers, that the gospel I preached is not something that man made up. 12I did not receive it from any man, nor was I taught it; rather, I received it by revelation from Jesus Christ.

Galatians 2 reads:

1Fourteen years later I went up again to Jerusalem, this time with Barnabas. I took Titus along also. 2I went in response to a revelation and set before them the gospel that I preach among the Gentiles. But I did this privately to those who seemed to be leaders, for fear that I was running or had run my race in vain. 3Yet not even Titus, who was with me, was compelled to be circumcised, even though he was a Greek.

4This matter arose because some false brothers had infiltrated our ranks to spy on the freedom we have in Christ Jesus and to make us slaves. 5We did not give in to them for a moment, so that the truth of the gospel might remain with you. 6As for those who seemed to be important—whatever they were makes no difference to me; God does not judge by external appearance—those men added nothing to my message. 7On the contrary, they saw that I had been entrusted with the task of preaching the gospel to the Gentiles,[a] just as Peter had been to the Jews.[b]

Are there false brethren among us today that have infiltrated our ranks to spy on the freedom we have in Christ and make us slaves?

If so, Do they preach another gospel?
