“ You must repent and be baptized, in the name of Jesus Christ;
42 For all men must repent and be baptized, and not only men, but women, and children who have arrived at the years of accountability.
43 And now, after that you have received this, you must keep my commandments in all things;
44 And by your hands I will work a marvelous work among the children of men, unto the convincing of many of their sins, that they may come unto repentance, and that they may come unto the kingdom of my Father. ”

“ History of the Church 1:60-64.
1 Now, behold, because of the thing which you, my servant Oliver Cowdery, have desired to know of me, I give unto you these words:
2 Behold, I have manifested unto you, by my Spirit in many instances, that the things which you have written are true; wherefore you know that they are true.
3 And if you know that they are true, behold, I give unto you a commandment, that you rely upon the things which are written;
4 For in them are all things written concerning the foundation of my church, my gospel, and my rock. ”
