Ebenezer Robinson, explaining in the Return a statement signed by him and his wife in October, 1842, to offset Bennett's charges, in which they declared that they "knew of no other form of marriage ceremony" except the one in the "Book of Doctrine and Covenants," said that this statement was then true, as the heads of the church had not yet taught the new system to others. But they had heard it talked of, and the prophet's brother, Don Carlos, in June, 1841, had said to Robinson, "Any man who will teach and practise spiritual wifery will go to hell, no matter if it is my brother Joseph." Hyrum Smith, who first opposed the doctrine, went to Robinson's house in December, 1843, and taught the system to him and his wife. Robinson was told of the "revelation" to Joseph a few days after its date, and just as he was leaving Nauvoo on a mission to New York. He, Law, and William Marks opposed the innovation. He continues: "We returned home from that mission the latter part of November, 1843. Soon after our return, I was told that when we were gone the 'revelation' was presented to and read in the High Council in Nauvoo, three of the members of which refused to accept it as from the Lord, President Marks, Cowles, and Counsellor Leonard Soby." Cowles at once resigned from the High Council and the Presidency of the church at Nauvoo, and was looked on as a seceder. Robinson gives convincing testimony that, as early as 1843, the ceremonies of the Endowment House were performed in Nauvoo by a secret organization called "The Holy Order," and says that in June, 1844, he saw John Taylor clad in an endowment robe. He quotes a letter to himself from Orson Hyde, dated September 19, 1844, in which Hyde refers guardedly to the new revelation and the "Holy Order" as "the charge which the prophet gave us," adding, "and we know that Elder Rigdon does not know what it was." * * The Return, Vol. II, p. 252. We may find the following references to this subject in Smith's diary: "April 29, 1842. The Lord makes manifest to me many things which it is not wisdom for me to make public until others can witness the proof of them." "May 1. I preached in the grove on the Keys of the Kingdom, etc. The Keys are certain signs and words by which the false spirits and personages can be detected from true, and which cannot be revealed to the Elders till the Temple is completed." "May 4. I spent the day in the upper part of my store... in council with (Hyrum, Brigham Young and others) instructing them in the principles and order of the Priesthood, attending to washings, anointings, endowments.... The communications I made to this Council were of things spiritual, and to be received only by the spiritually minded; and there was nothing made known to these men but what will be made known to all the Saints of the last days as soon as they are prepared to receive, and a proper place is prepared to communicate them." * * Millennial Star, Vol. XIX, pp. 390-393.
