The classic repeat-after-me exchange
Officiant-led · about 3 minutes with both partners
Officiant: [Partner A], please repeat after me.
I, [name] · take you, [name] · to be my wife · to have and to hold · from this day forward · for better or for worse · for richer or for poorer · in sickness and in health · to love and to cherish · till death do us part.
Officiant: [Partner B], please repeat after me.
I, [name] · take you, [name] · to be my husband · to have and to hold · from this day forward · for better or for worse · for richer or for poorer · in sickness and in health · to love and to cherish · till death do us part.
The phrasing is broken into repeatable chunks on purpose. Do not join them back up — long phrases are where people lose their place.
