What does Yogananda say about all the contradictions that are in the bible ? This is one of many examples: John 10:30, "I and my Father are one." And John 14:28. "Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I."
Dear Feo, Yes, you are right. There are many seeming contradictions in the Bible.
Paramhansa Yogananda says that the Bible is a holy scripture in part, but that it was written by many different people, not all of whom were spiritually enlightened. And of course, the Bible is thousands of years old and has gone through many transitions and translation—a process which has certainly “muddied the waters,” at least to some degree.
Yogananda’s suggestion is that we study the Bible (and other scriptures also) with the help of interpretations and explanations offered by a God-realized Master, such as he himself was. They can explain what was really meant by a contradiction such as the one you have mentioned—there are often deeper levels of meaning, which are not easily revealed, except by a great master.
