Are you kidding me? How many other people that day DID NOT receive the Holy Spirit? That would be everyone else in the world. Other than the Apostles, she is the ONLY one NAMED out of all of the people who were present. This is displays some significance. This may not seem like a big deal to you, but it is. Whoever continues to discredit the Mother like this (i.e she is just a vessel, she's not "special") insults the Son.
Everyone did. That's how they were able to speak in toungs. It decended on the whole crowd, like flames upon their heads. Guess you missed that day, aye?

Imagine the list if all names were used. Get real. Why list everyone at the meeting? Does the press report everyone at a campain rally?
