Situation
An opponent has the commander Edgar Markov:
Eminence — Whenever you cast another Vampire spell, if Edgar Markov is in the command zone or on the battlefield, create a 1/1 black Vampire creature token.
I play Ethereal Absolution:
Creatures you control get +1/+1.
Creatures your opponents control get -1/-1.
So whenever he plays a vampire, he creates a 1/1 token that immediately dies to my enchantment.
Next turn, he plays Captivating Vampire:
Other Vampire creatures you control get +1/+1.
Interpretations
According to my opponent, whenever he plays a vampire the 1/1 vampire tokens now do survive as they enter the battlefield with a +1/+1 on them (from the Captivating Vampire).
According to me, his vampire tokens still die after entering the battlefield. As soon as they hit the battlefield they become 0/0 creatures due Ethereal Absolution: creatures with 0 toughness go to the graveyard. I say this happens before the tokens get their +1/+1 bonus, since the Captivating Vampire doesn't state that other vampires enter the battlefield with that bonus.
Clearly we were both biased to a ruling that's beneficial to ourselves. We went for his ruling, because he's the more experienced player. But what do the rules actually say about this situation? Is anyone correct?
In other words: when exactly does the "get +1/+1" from Captivating Vampire and "get -1/-1" from Ethereal Absolution happen once a 1/1 vampire gets summoned? And in which order to they happen?
