“Father Adam’s oldest son (Jesus the Savior), who is the heir of the family, is Father Adam’s first begotten in the spirit world. Who, according to the flesh, is the only begotten as it is written. (In his divinity he having gone back into the spirit world, and come in the spirit to Mary and she conceived, for when Adam and Eve got through with their work in this earth, they did not lay their bodies down in the dust, but returned to the spirit world from whence they came.)”
