Attended conference, a very interesting conference, for at this meeting President Brigham Young said thus, that Adam and Eve were the names of the first man and woman of every earth that was ever organized and that Adam and Eve were the natural father and mother of every spirit that comes to this planet, or that receives tabernacles on this planet, consequently we are brother and sisters, and that Adam was God, our Eternal Father. This as Brother Heber remarked, was letting the cat out of the bag, and it came to pass, I believed every word, for I remembered saying to the Brethren at a meeting of High Priests in Nauvoo, while I was speaking to them under the influence of the Spirit, I remarked thus, that our Father Adam had many wives, and that Eve was only one of them, and that she was our mother, and that she was the mother of the inhabitants of this earth, and I believe that also, but behold ye there were some that did not believe these sayings of the Prophet Brigham, even our Beloved Brother Orson Pratt told me he did not believe it. He said he could prove by the scriptures it was not correct. I felt very sorry to hear Professor Orson Pratt say that. I feared least he should apostatize, but I prayed for him that he might endure unto the end, for I knew verily it was possible that great men might fall. I remembered Apostle John E. Page. I saw him take from his pocket a plug of tobacco and bite a mouthful and put it back. It surprised me. I said old chap you will apostatize, but still I really hoped he would not, but he is gone, and I am very sorry for the poor man.
