Doug, after thread after thread of isolated verses, manufactured contradictions, and conclusions that ignore the surrounding context, you are starting to look less like someone seeking truth and more like someone determined to force a system onto Scripture. The Bible repeatedly warns us to be careful with teachers who distort God's word (2 Peter 3:16), teach things contrary to sound doctrine (1 Timothy 1:3), or divide believers through speculative interpretations (Titus 3:9).
Please examine yourself carefully in light of these warnings. None of us should want to stand before God and discover that we handled His word carelessly or led others into error.
As for your claim, the fact that baptism is mentioned in one context and not emphasized in another does not create two gospels. By that logic, every time one biblical author mentions a detail another author does not, we would have multiple gospels.
Paul explicitly taught there is only one gospel. In Galatians 1:8-9 he pronounces a curse on anyone who preaches another gospel. If there were two legitimate gospels, Paul's warning makes no sense.
Your argument also ignores the fact that Paul himself baptized converts (1 Corinthians 1:14-16). Therefore, baptism cannot be what separates Paul's gospel from that of Jesus and the apostles.
The difference is not two gospels. The difference is emphasis. John the Baptist, Jesus, the Twelve, and Paul all proclaimed salvation through God's redemptive work. You are taking a ministry distinction and turning it into a gospel distinction, and the text simply does not support that conclusion.
