Soft-spoken Jason Castro, a junior at Texas A&M, was inducted into the Aggie Mens Club this past fall -- an organization that provides a "social atmosphere of Christian fellowship and brotherhood." They're currently on a trip to Honduras, donating time and money ($14,000) to build homes and orphanages.
TMZ spoke to Chris, the Club's president, who's now in the country's poverty-stricken capital, Tegucigalpa. Chris spoke highly of Jason -- saying Jason would likely have joined the 14 guys who are in Honduras right now ... but for "Idol."
BTW, the guys way down south caught Jason's performance Tuesday night -- thank God for Honduras cable.
