I'd love to play this as my wedding ceremony, it's one of the few I would get away with without it being deemed too secular since being Catholic and having a very close-knit Catholic family, I am kind of expected to marry in the Church. Fortunately, there is some room for personalization so it isn't completely cookie-cutter.
Maybe about not being hurt no more or something but I guess it would always remain as a philosophical mystery.
In a objetive point of view for example love can be interpreted in a very cynical way, either extremely selfish or selfless, we like to talk about love like if it's a simple "thing" we all know about, but then why are different "types" of love? (love for a friend, for a lover or for a child for example?), why some people would die for love or kill in it's name?
In the end it can be just an ilusion, just like a cold, nothing but a biological sympton we need to survive as an specie, a pre-coded feeling with the proporse to protect our own and procreate... hell, even the love to ourselves, the wish of living could mean we are nothing but slaves of nature, slaves of the enigma poeple has been calling life since thousands of years, and the meanest guard yanking our chains is nothing but the most beautiful thing we know... or well whatever, I better stop with this nonesense.
