"Most people are well acquainted with the history of Jesus Christ Who was born nearly two thousand years ago in Palestine. There are, however, some aspects of His life that are not so commonly known and which date back to long before the period of His biblical life on Earth. It should be realised that the Entity who made His appearance on Earth two millennia ago... had a long preceding course of development to enable Him to attain such an advanced state of enlightenment. To describe the Christ merely as a Son of God is rather meaningless and inadequate, because we are really all children of God (even though many may not seem to act accordingly)."
