Here "vested" means "given to" or "authorised by". It's not common in casual conversation. It's used by those with authority. It's a well-known line for the priest to say in wedding ceremonies! You can also use "vested" to mean a personal interest in the success of something. Ex: By the power vested in me, I pronounce you husband and wife. => By the power given to me. Ex: The government has vested authority to look after its citizens. Ex: I have a vested interest in the success of your business. Ex: I'm vested in my studies. I need to do well!
