This must really be important.

The fact that this passage was repeated pretty much word for word two chapters in a row makes me think that it was important.  It was being emphasized. 

Acts 11:4-18(NKJV)

But Peter explained it to them in order from the beginning, saying: 

“I was in the city of Joppa praying; and in a trance I saw a vision, an object descending like a great sheet, let down from heaven by four corners; and it came to me. 

When I observed it intently and considered, I saw four-footed animals of the earth, wild beasts, creeping things, and birds of the air. 

And I heard a voice saying to me, ‘Rise, Peter; kill and eat.’ 

But I said, ‘Not so, Lord! For nothing common or unclean has at any time entered my mouth.’ 

But the voice answered me again from heaven, ‘What God has cleansed you must not call common.’ 

Now this was done three times, and all were drawn up again into heaven. 

At that very moment, three men stood before the house where I was, having been sent to me from Caesarea. 

Then the Spirit told me to go with them, doubting nothing. Moreover these six brethren accompanied me, and we entered the man’s house. 

And he told us how he had seen an angel standing in his house, who said to him, ‘Send men to Joppa, and call for Simon whose surname is Peter, 

who will tell you words by which you and all your household will be saved.’ 

And as I began to speak, the Holy Spirit fell upon them, as upon us at the beginning. 

Then I remembered the word of the Lord, how He said, ‘John indeed baptized with water, but you shall be baptized with the Holy Spirit.’ 

If therefore God gave them the same gift as He gave us when we believed on the Lord Jesus Christ, who was I that I could withstand God?”

When they heard these things they became silent; and they glorified God, saying, “Then God has also granted to the Gentiles repentance to life.”

As I read the selection more carefully I realized that I had misread it before.  For some reason I had it in my head that God said "what God has MADE you must not call common.". 

Not so!

It says "what God has cleansed you must not call common.". 

You might be saying so what?  Here is why it makes a difference in my mind.

There are some who argue that we shouldn't criticize anybody because "God made us all".  I used to think that the Scripture above backed up their view.  Now that I have read and understood it correctly, I can see it doesn't back up their view at all.
