Most Christian churches and sects have claimed a spiritual monopoly. The main foundation for this claim is the sixteenth verse of the third chapter of John where the Evangelist says that Jesus is "the only begotten son of God." But nowhere in the New Testament does Jesus himself make the same assertion. On the contrary, he went out of his way to tell men, "The works that I do shall ye do also," thus refusing to put himself in a unique separate and unattainable species, which would make it impossible for other men to imitate his example or hope to attain his understanding.
