14. The First Conference.--The first conference of the church was held the first day of June, 1830. About thirty members were in attendance, besides a number of unbaptized believers and others anxious to learn. The sacrament was administered, a number who had been baptized were confirmed, {309} and brethren were called and ordained to various offices of the priesthood. The time was spent in prayer, singing, instruction and exhortation. The Holy Ghost was abundantly poured out upon the saints. Some prophesied, and others were wrapped in heavenly vision, until their bodily strength was exhausted. When restored they shouted hosannah to God and the Lamb, and related the glorious things they had seen and felt while in vision. [See note 4, end of section.] Thus the ministry of God's servants began to be confirmed by the signs and the gifts of the Holy Ghost following those who believed. 15. Errors of the Saints.--It would be unreasonable to suppose that the members of the church fell into no errors. Some time in the summer of 1830, while the prophet was still living in Harmony, Penn., and Oliver Cowdery was with the Whitmer family in New York, he received a letter from Oliver informing him that he [Oliver] had discovered an error in one of the revelations, and added: "I command you in the name of God to erase these words [having named the passage] that no priestcraft be among us." [37] The prophet wrote immediately, asking by what authority Oliver took it upon himself to command him to alter or erase, to add to, or diminish a revelation or commandment from Almighty God. Joseph followed his letter in a few days, and was grieved beyond measure to find that the whole Whitmer family sustained Oliver in the position he had taken. By labor and perseverance, however, he convinced them that they were in error and the difficulty was settled.
