My name is [Celebrant's full name] and I am duly authorised by law to solemnise marriages according to law and to officiate at your marriage today. I take this opportunity to wish you both much happiness in your future lives together.

Much like wedding celebrant, wedding officiant is a broad term to describe someone who leads a wedding ceremony. Not everyone who refers to themself as a wedding officiant can legally register your marriage, however, some solemnisers who can legally register your marriage (see What Does a Wedding Solemniser Do?)

A celebrant is a person who performs ceremonies marking some of life's biggest milestones. As well as officiating weddings, celebrants often perform vow renewals, baby naming ceremonies and funerals. For weddings, a celebrant will create a bespoke, meaningful ceremony that isn't religious.
