It is easier when you have a non-denominational wedding, or an independent priest officiating your wedding, otherwise you might just be stuck with the lithurgy, or whatever is in the wedding solemnization catechism for your denomination. I wed in the Anglican church where my dad is a knight, still I managed to change around a few things, for instance I did not vow to obey, and one or two other lines. Luckily the Bishop read from our program rather than the Book of Common Prayer and did not notice. BTW, I'm still vexing that he skipped the "you may kiss the bride" part. Moving on...
I just read about Tuface and Annie Idibia's wedding vows and I was tripping.
TuFace Idibia
Many years ago I was farther than the eyes could see.
Now we are now in that future
When I look into your eyes, I still see
You came into my life and you lit it up
Like the sun, like the moon, like the stars
All the words in the dictionary
All the words in this world can not be enough
To say what my heart feels for you.
But all I can say is baby, my heart is like a stereo right now
And it will beat only for you till death do us part.
I love you baby.
