Yogananda said he came to bring the original teachings of Jesus Christ and the original teachings of Krishna and to show the unity between them. He put Christ at the center of the SRF altar, he names Christ first in the line of gurus, and he said it was Christ himself who appeared to Babaji and asked that this teaching of Self-Realization be sent to the West. Yogananda wrote an extensive commentary on the Christian Bible, which SRF still has not published in book form. In his other writings and his public lectures he frequently refers to Jesus and his teachings. Yogananda went so far as to call his mission the "Second Coming of Christ."
