Christ was crucified in approximately 33AD and Paul started his ministry in approximately the forties AD, not much more than 10 years after Jesus's teachings.
If you are saying that Paul's teachings were adjusted for a different period the ink on the written word recorded for Jesus hardly had time to dry when it had to be changed which is especially mystifying considering the time lag between Jesus actually teaching and when the teachings were recorded.
The differences between what Jesus and Paul taught was not exactly trivial and we are left to wonder why there was such a profound and important difference.
