conversely, such funding has come under attack through comments by john castellani, the former president of teen challenge usa, during a house government reform subcommittee, examining the efficacy of religious social service providers. during the hearing, castellani said teen challenge does not hire non-christians as employees and, when asked if the group takes non-christians as clients, he said yes, and boasted that some jews who finish his teen challenge program become "completed jews." the "completed jews" phrase has been used by some christians and messianic jews to refer to people who previously followed judaism and have become believers in yeshua (jesus); many jewish groups consider it offensive because of the implication that those who don't believe in jesus are "incomplete". critics of faith-based funding cite this as an example of how religious intolerance could be publicly funded.
