In the revelation of December 27, 1833 (Doc. and Cov. Sec. 88), the elders of the Church were also commanded to "teach one another the doctrines of the kingdom." They were to be instructed "more perfectly in theory, in principle, in doctrine, in the law of the Gospel, in all things that pertain unto the kingdom of God," that were expedient for them to understand. They were to tarry in Kirtland for this instruction, before they should "go forth, among the Gentiles for the last time, as many as the mouth of the Lord shall name, to bind up the law and seal up the testimony, and to prepare the Saints for the hour of judgment which is to come." They were to seek diligently out of the best books, words of wisdom and learning "even by study and also by faith." That this should be accomplished, they were to prepare a house of prayer, learning and faith, even a house of glory--a house of God. In it they were to call their solemn assemblies; one should be appointed as teacher, and not all speak at once. While one speaks, all others should give attention. In this manner there was to be perfect order in the School of the Prophets--for so it should be called. Moreover, the Lord declared: "And this shall be the order of the house of the presidency of the school: He that is appointed to be president, or teacher, shall be found standing in his place, in the house which shall be prepared for him. Therefore, he shall be first in the house of God, in a place that the congregation in the house may hear his words carefully and distinctly, not with loud speech." Those who were entitled to attend should be the officers of the Church who are called to the ministry, "beginning at the high priests, even down to the deacons." They were to greet each other in fellowship, with proper salutations. They should be men who were clean from the blood of this generation, sober-minded and full of faith. Further, the Lord stated: "And ye are called to do this by prayer and thanksgiving as the Spirit shall give utterance in all your doings in the house of the Lord, in the School of the Prophets, that it may become a sanctuary, a tabernacle of the Holy Spirit to your edification."
