I realized that the context I thought to be common is actually not, if you excuse me, this will be a little long to explain. In order to comprehend the nature of commitments, oaths, and words from a satanic perspective, first I should tell what I'm taught about them so someone can correct me if I'm wrong.
Names are powerful. The tales of old tell us the stories of people searching the names of creatures to master them so they can call for them. It's to a degree that knowing someone's ''real name'' could give you power over that person. There are warnings to never reveal your ''real name'' to a magician because they know how to use names. I don't know if this ''real name'' concept has roots or was invented by the witches in the dark ages to avoid exposing themselves to dangerous times. The latter, probably.
According to another theory, the real name is one's birth name. The name your parents or whoever was taking care of you used to call you. The name your vulnerable baby brain recognize as themselves before starting to think consciously. A name you know to be you in your subconscious which makes it easier to use hypnosis on you or program your mind.
In the stories of random nomad storytellers in the desert or Shakespeare, there is always a strong emphasis on the words used while making a promise. Fae/Genie takes the words very literal. God taught Adam the names of all things to prove he is worthy to be bowed - be it just a fake tale or allegory.
In her sermon Spirit Abuse, High Priestess Pythia mentions that Satan is very serious about keeping his end of the deal. This pushes me to think those stories may have right in them. The name Satan means truth. If the words indeed have powers in them, the powerful demon/god we call Satan has to be true about everything. This is why I'm here in the first place. However, it's not certain that if the promises and words are binding through their own power or we are the ones who make them mean anything.
Think about that: If you sign an agreement and don't keep your end, or lie to someone, or betray, it's the police and man-made laws that punish you. Not a bolt of lightning from the skies or any punishment by the universe itself. I'm questioning that if promises can be binding without anyone executing any punishment and ignoring the concepts like guilt and honor, maybe thanks to the energy that attributes meanings to the words by countless minds or as a rule of the universe itself. Didn't you wonder why magic is also called ''spell'' in English?
The other question regards changing names. Keep what I stated above about birth name. There is a story, not an old one, a man abandoned his name (or his values) and lost his magick, his control on the air element as a result. The author may not know a thing about magic but what our souls brought from our past lives and what humankind was able to save from the destruction of memory and history. I still find the story very interesting.
A new life comes with a new name. Starting a new life means giving up the old one, burying what we learn throughout a lifetime to the depths of the mind. If we associate the new name and birth, which makes sense to me, it becomes inevitable of the end, death, farewell to the past, a fall, abandonment, leaving...
I should learn to keep it short. There is a common understanding that children carry their names in my native. You can hear a mother-in-law saying ''I told you not name him Storm (Bora)! I bet a real storm couldn't do what he did to the living room...'' any time. Back then, they didn't name boys until they came back home after a fight/war or did something honorable. Rite of passage into adulthood was a thing and you had to earn your name.
With all these aspects, think about the situation of someone with a name like ''a slave to YHWH''. Luckily not me but I know more than a few people.
To sum it up, do oaths and words solely depend on what we have common in understanding to call things with names and our acts to perform them or do meaning and the power of the words is something more... independent? Though the oblivious masses' minds may indirectly give power to the words of any language with their own energy causing the same thing anyway...
Vibrating mantras, old languages... I really hope someone who has a better understanding of words and voices can give a clearer version of what I'm trying to explain and ask.
