I pronounce you man and wife.
You, as the man, are still a full-fledged individual with the aspirations, rights, successes and failures that come from individuality. The woman, however, now only exists in terms of you. She is your property, her aspirations are whatever your aspirations are, her rights are what you say they are, and so on.
But we dont say I pronounce you man and wife anymore. It has been replaced, in most cases, by the phrase I pronounce you husband and wife. Its a small changesomething that I hadnt even noticed until I looked into itbut I want to know if it is a meaningful one.
