You can have the flowers and the cake and the attendants but that still doesn’t make you married.
It’s the ceremony that makes you married.
The ceremony actually changes your state of being. Before the ceremony you are single people. After the ceremony you are a wife or a husband and together you are a married couple.

I am a Celebrant and I know but I can’t tell you because it’s a secret.
Oh, alright, since you asked so nicely, I’ll tell you – It’s actually magic!
