Once again, who you gonna believe, Paul or Jesus?

Here is another example of where I believe Paul is contradicting Jesus.  In these verses Paul is essentially shun and separate yourselves from these sinners. 

1 Corinthians 5:9-13(NKJV)

I wrote to you in my epistle not to keep company with sexually immoral people. 

Yet I certainly did not mean with the sexually immoral people of this world, or with the covetous, or extortioners, or idolaters, since then you would need to go out of the world. 

But now I have written to you not to keep company with anyone named a brother, who is sexually immoral, or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner—not even to eat with such a person.

For what have I to do with judging those also who are outside? Do you not judge those who are inside? 

But those who are outside God judges. Therefore “put away from yourselves the evil person.” 

Now let's compare that to these verse where Jesus spoke on the subject.

Mark 2:15-17(NKJV)

Now it happened, as He was dining in Levi’s house, that many tax collectors and sinners also sat together with Jesus and His disciples; for there were many, and they followed Him. 

And when the scribes and Pharisees saw Him eating with the tax collectors and sinners, they said to His disciples, “How is it that He eats and drinks with tax collectors and sinners?”

When Jesus heard it, He said to them, “Those who are well have no need of a physician, but those who are sick. I did not come to call the righteous, but sinners, to repentance.”

Who you gonna believe?  I chose Jesus!
