LDS Articles of Faith: 5

We believe that a man must be called of God, by prophecy, and by the laying on of hands by those who are in authority, to preach the Gospel and administer in the ordinances thereof.

I do believe a man (or woman) must be called of God to preach the Gospel. However, I believe that calling comes as inspiration to that person. Again, I don't believe in ordinances, beyond being symbolic teaching messages.

I don't believe the laying on of hands is important. I don't think one man can give this type of authority to another man. I believe that teaching truth comes from the inside and is directly between you and God.
