Being in a fraternity while under 21

Hello Greek rank dot com.

I am interested at Cornell in 'rushing' an IFC Cornell affiliated fraternity at Cornell. Due to my nature as a Freshman, I am 19 years of age currently at Cornell. Therefore, it is illegal for me (and my fellow peers) to consume alcohol, except during Church services. My question is as follows: how do underage students participate in social events while not drinking? Are there board games and/or hors d'oeuvres to keep us occupied? Thank you in advance, fellow Cornellians. Go Big Red, and God protect our troops.
