To the readers:
You have lost 1 Corinthians 10:4 & 9 as a proof text for the pre-existence of Jesus.
1 Cor. 10:4 says it's a spiritual rock, i.e., not a person. And there is not a person named Christ following the Israelites around in the desert. The Christ or Messiah is a human and didn't exist until after his birth. He wasn't made Christ until after he was already human according to Acts 2:36. The Messiah didn't pre-exist as the Messiah so the idea of Christ being a spiritual rock that followed them is either prophetic or a misnomer. It's not a misnomer, therefore you're flatout wrong.
The word "Christ" doesn't exist in the manuscripts for 1 Corinthians 10:9 because it doesn't make any sense if it does. If it did, it would be another misnomer because the Christ didn't exist yet. Pretty difficult to anger a non-existent being. The best versions of 1 Cor. 10:9 say "the Lord" in reference to the Father, not Jesus.
1 Cor. 10 (NASB)
9Nor are we to put the Lord to the test, as some of them did, and were killed by the snakes.
