He told me that At one wedding--the person conducting the ceremony decided to use his own words--and my dad stopped him and insisted he use the exact words in the script. I dont think he was too popular after that.
I heard of a case like that during a recent JW wedding. The "authorised person" was also a JW, and was also a stickler for the rules like your dad (rightly so, IMO). It wasn't as bad as the bro taking the service using his own words, but apparently what happened was that the bro was either underprepared or nervous and accidentally mis-spoke - leaving out some words or something similar - and the AP interrupted him and made him go right back and start over again.
Funny how only the vows for the wife mention respect.
This is based on the scripture at Ephesians 5:33 "Nevertheless, each one of you must love his wife as he does himself; on the other hand, the wife should have deep respect for her husband."
I suppose the idea is because the husband is supposedly the "head" of the marriage, having respect is considered more important towards someone "taking the lead".
But yes, respect should be a basic requirement on both sides (and come to that, in every family relationship - between kids and parents too).
