Q: What is the most authentic document of Jesus’ teaching? The Gospel of Thomas? Are there others you would point to?
The Gospel of Thomas seems to be the most authentic. Certainly the four Gospels of the Bible contain his teachings, but mixed in with untrustworthy elements. Still, they should be read with the understanding that the sugar must be separated from the sand, as Sri Ramakrishna said about all scriptures. [Read The Gospel of Thomas for Awakening on our website or in print.]
The Second Coming of Christ by Yogananda [Available for download on our E-library] is invaluable in understanding Jesus’ teachings, as is his autobiography and the books of his public talks [see our post A Yogi’s Recommended Reading List.]
The Aquarian Gospel of Jesus the Christ is a remarkable document that does not claim to be infallible, but is also invaluable in understanding Jesus and the difference between THE Christ and A Christ. [Read online on our website and also The Aquarian Gospel for Awakening, a commentary.
The Unknown Life of Jesus Christ seems to be very much conformed to the idea of the narrators. Still, it is good to look into.
In The Christ of India the quotation from the Bhavishya Mahapurana is short but certainly authentic. There we see what Jesus thought of the religion of his land of birth and his definite adoption of Sanatana Dharma. [Also available in print.]
