As stated, all six of the original members of the Church were again baptized on the day of the organization. This action was due, in part at least, to the fact that baptism is the doorway into the Church as well as for the remission of sins. There had been a few others baptized before the sixth of April (see Ch. 9). Some of those previously baptized raised the question as to why they should again be baptized. In consequence of their desire to unite with the Church without re-baptism, the Prophet inquired of the Lord in relation to the matter and received the following revelation: "Behold, I say unto you, that all old covenants have I caused to be done away in this thing, and this is a new and an everlasting covenant, even that which was from the beginning. Wherefore, although a man should be baptized an hundred times, it availeth him nothing, for you cannot enter in at the strait gate by the law of Moses, neither by your dead works; For it is because of your dead works, that I have caused this last covenant and this Church to be built up unto me, even as in days of old. Wherefore, enter ye in at the gate, as I have commanded, and seek not to counsel your God. Amen" (Doc. and Cov. sec. 22). Chapter 13 Beginning of the Public Ministry of the Church 1830 The First Public Discourse On Sunday, April 11, 1830, the work of proselyting was publicly launched. The first discourse was preached by Oliver Cowdery. The meeting was held by appointment at the home of "Father" Peter Whitmer, where the meeting of organization had been held the Tuesday preceding. A goodly number of members and investigators were present. The impression made on the minds of those assembled was favorable, and the same day Hiram Page, Katherine Page, Christian Whitmer, Anne Whitmer, Jacob Whitmer and Elizabeth Whitmer, were baptized. One week later (April 18) Peter Whitmer, Sen., Mary Whitmer, William Jolly, Elizabeth Jolly, Vincent Jolly, Richard B. Preston and Elizabeth Ann Whitmer, were added to the Church.
