Did Paul teach a different Gospel?

Why do the teachings of Messiah contradict "Christian" doctrine and why do those that subscribe to these doctrines constantly point to Paul? Which Path leads to eternal life and which one leads to destruction?

It's interesting that there are 2 people in what are called "The New Testament" writings that stand out above the rest. The first is of course Yahshua the Son of Yahweh and the second is Paul. Yahshua was anointed (Meshiaced in the Hebrew and written as Messiah or Christ in English Bibles) for the sole reason to preach the one and only true Gospel.
Luk 4:17 And there was delivered unto him the book of the prophet Isaiah. And when he had opened the book, he found the place where it was written,
Luk 4:18 The Spirit of Yahweh is upon me, because HE HATH ANNOINTED ME TO PREACH THE GOSPEL to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,
Luk 4:19 To preach the acceptable year of Yahweh.
Luk 4:20 And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him.
Luk 4:21 And he began to say unto them, This day is this scripture fulfilled in your ears.
Yahweh also spoke of this coming Prophet through Moses.
Deu 18:18 I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.
Deu 18:19 And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.
This is a strongly worded warning for those that choose not obey the Gospel. We see this clear warning as it pertains to Yahshua but where does this leave Paul's writings? An interesting fact is that out of 40 writers in the Bible Paul is the only one to have a specific type of warning. This warning is given by Peter.
2Pe 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
2Pe 3:14 Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless.
2Pe 3:15 And account that the longsuffering of our Master is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you;
2Pe 3:16 As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest(twist), as they do also the other scriptures, unto their own destruction.
2Pe 3:17 Ye therefore, beloved, seeing ye know these things before, BEWARE lest ye also, being led away with the error of the wicked(Lawless), fall from your own stedfastness.
2Pe 3:18 But grow in grace, and in the knowledge of our Master and Saviour Yahshua the Messiah. To him be glory both now and for ever. Amen.
Peter had a personal relationship with Paul, calling him beloved. He also lived in the same era and had intimate communication with, and knowledge of, the small groups of people that Paul was writing letters to. Given all this, he thought that certain parts of Paul's letters were hard to understand, and even in that day, people that were unstable and unlearned were twisting to their own destruction. Peter calls this the error of the "athesmos"(lawless). Peter gives us the antidote to this error which is to grow in the grace and in the knowledge of the Master and Savior Yahshua the Messiah. If we grow in His knowledge our house will be built upon the Rock and we will not be unstable or unlearned.
Mat 7:24 Therefore whosoever heareth THESE SAYINGS OF MINE, and doeth them, I will liken him unto a WISE man, which built his house upon a rock:
Mat 7:25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
Mat 7:26 And every one that heareth THESE SAYINGS OF MINE, and doeth them not, shall be likened unto a FOOLISH man, which built his house upon the sand:
Mat 7:27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and GREAT WAS THE FALL OF IT.
In Paul's letters he is constantly Pointing to Messiah and the Gospel. He was not trying to start a new religion that was focused around himself. He was pointing people to the Truth.
1Co 1:12 Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
1Co 1:13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
1Co 1:14 I thank Elohim that I baptized none of you, but Crispus and Gaius;
1Co 1:15 Lest any should say that I had baptized in mine own name.
Paul's letters can truly be hard to understand in that in some places he seems to say one thing and in other places he seems to contradict what was just said and a lot of the times it's in the very same letter. Paul was chosen specifically by Yahshua the Master to bear His name not only before the Gentiles but also before the children of Israel. Paul also constantly warned of false teachers even calling them ravenous wolves. It's sad that his writings have been used by so many to teach contrary to the testimony of Yahshua.
2Th 1:7 And to you who are troubled rest with us, when the the Master Yahshua shall be revealed from heaven with his mighty angels,
2Th 1:8 In flaming fire taking vengeance on them that know not Elohim, and that obey not the gospel of our Master Yahshua the Messiah:
2Th 1:9 Who shall be punished with everlasting destruction from the presence of the Master, and from the glory of his power;
2Th 1:10 When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day.
There is only 1 Gospel and there is only one Messiah (Anointed to preach that Gospel). It is an everlasting Gospel and according to Paul anybody preaching another gospel is accursed.
Gal 1:8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
This is in direct disagreement with what most religious organizations teach but it is in perfect agreement with the doctrine of Christ.
Joh 12:47 And if any man hear MY WORDS, and believe not, I judge him not: for I came not to judge the world, but to save the world.
Joh 12:48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: THE WORD WHICH I HAVE SPOKEN, the same shall judge him in the last day.
Joh 12:49 For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak.
Joh 12:50 And I know that HIS COMMANDMENT IS EVERLASTING LIFE: whatsoever I speak therefore, even as the Father said unto me, so I speak.
According to the above quote, to reject Messiah's Word is to reject Him and that very same Word that has been spoken and recorded for all in our bibles will judge those of us that reject Him on that last day. His commandment is everlasting life if we hearken to His voice.
Joh 10:27 My sheep HEAR MY VOICE, and I know them, and THEY FOLLOW ME:
Joh 10:28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
