So, what is the difference between a licensed minister and a licensed wedding officiant? Basically, an ordained minister is ordained by the Church or ministerial association and meets certain requirements for being ordained. An ordained minister is able to perform various duties of the church and other functions of its faith, including funeral ceremonies, sacraments, and legal weddings. However, a licensed wedding officiant is likely only permitted to officiate at weddings or other marriages. A wedding is a religious ceremony, and traditionally a minister officiates over it.
