It's love your neighbor as youself, it's right there in James 2. In 1 Cor 11 Paul says some of you are sick and some sleep (died), why, and it's in the immediate context.
You would have to actually read them, and it will all make sense. In James 2 there is mention of the Royal Law, why were some of the Corinthians sick and some of them dead? It's in 1 Cor. 11, try reading it.
But what are the works James is talking about, or Paul for that matter, that's the point. James presided over the Council of Jerusalem and Peter made the crucial and decisive argument for justification by faith. James made the recommendation that a letter be sent to the newly formed Gentile churches discussing circumcision and how it relates to the gospel. Paul wrote that letter, the first book of the New Testament and he was there telling the Apostles about the work God had been doing over the course of the first missionary journey.
Well since Scripture cannot contradict itself, Paul speaks of justification before God, whereas James speaks of how men see evidence of that justification through good works.
Which is exactly what Paul was talking about when he said that justification was by apart from works, what was agreed at the Jerusalem Council and what Protestands mean justification by Grace throw faith alone. James are Paul are not talking about the same works, that's why there statements have to be read in context. The works James is talking about are the works of righteousness that are the fruit of salvation. In that society most people were slaves in your bigger cities. In James 2 and 1 Cor. 11 they had the exact same problem, how the rich treated the poor.
How can the man who wrote OVER HALF the New Testament be "half-right"? There is absolutely no conflict between Paul and James since they were addressing two different aspects of salvation. Here is how to look at it:
