I do not object to your right to pursue whatever course you choose and to believe whatever conclusions you reach. But I do question some of your statements upon which you base your premise.
1. There is no consensus among "modern scholars" as to the origin of Christian teachings. Scholars have as many theories as clergymen have doctrine.
2. If the scrolls that were found in and around Qumran prove not to be of the Essenes, then all your speculations about the Essenes being the main influence of Christian belief mean nothing.
In the past few years, we've heard of many theories about where Christ got his knowledge. A few years ago, speculation was made about Christ having travelled to India to learn from the great mystics. Theories and speculations come and go. But the New Testament remains the only reliable record of Christ and his teachings. In it, his birth, his early childhood and his ministry clearly shows the Jewish origins of his life and teachings.
